Driver distraction, defined as the diversion of attention away from activities critical for safe driving toward a competing activity, is increasingly recognized as a significant source of injuries and fatalities on the roadway. Additionally, the trend towards increasing the use of in-vehicle information systems is critical because they induce visual, biomechanical and cognitive Bay bear stadium webcam and may affect driving performance in qualitatively different ways.
Non-intrusive methods are strongly preferred for monitoring distraction, and vision-based systems have appeared to be attractive for both drivers and researchers. Many distraction detection systems only use a single visual cue and therefore, they may be easily disturbed when occlusion or illumination changes appear. Power point template asian, these algorithms should be included in an embedded device or system inside a car.
This is not a trivial task and several requirements must be taken into account: reliability, real-time performance, low cost, small size, low power consumption, flexibility and short time-to-market. The key points for the development and implementation of sensors to carry out the detection of distraction will also be reviewed.
This paper shows a review of the role of computer vision technology applied to the development of monitoring systems to detect distraction. Some key points considered as both future work and challenges ahead yet to be solved will also be addressed.
In addition to deaths on the roads, up to 50 million people incur non-fatal injuries each year as a result of road traffic crashes, while there are additional indirect health consequences associated with this growing epidemic.
Road traffic injuries are currently estimated to be the Drivers webcam dk vision nocturna leading cause of death across all age groups globally, and are predicted to become the seventh leading cause of death by [ 1 ]. Distracted driving is a serious and growing threat to road safety [ 1 ]. Collisions caused by distracted driving have captured the attention of the US Government and professional medical organizations during the last years [ 2 ]. The prevalence and identification as a contributing factor in crashes is seen as an epidemic of American roadways, in words of Ray LaHood, when he was US Secretary of Transportation in [ 3 ].
There is not an exact figure English manor porn statistics about accidents caused by inattention and its subtypes since studies are made in different places, different time frames and therefore, different conditions.
The studies referenced below show both the different statistics about inattention in general and those recorded when produced by distraction and fatigue in particular. The trend towards increasing the use of in-vehicle information systems IVISs is critical [ 9 ] because they induce visual, manual and cognitive distraction [ 10 ] and may affect driving performance in qualitatively different ways [ 11 ]. Additionally, the advancement and prevalence of personal communication devices has exacerbated the problem during these last years [ 12 ].
All these factors can lead to the increment of the number of tasks subordinate to driving activity. These tasks, namely secondary tasks, which may lead to distraction [ 13 ], include eating, drinking, the act of taking something or tuning the radio or the use of cell phones and other technologies. For example, the use of cell phones while driving, according to naturalistic studies [ 17 ], causes thousands of fatalities in the United States every year [ 1819 ].
The scope of the paper can be seen in Figure 1 and is commented as follows. The main methods for face detection, face tracking and detection of facial landmarks are summarized in Section 2 because they are a key component in many of the video-based inattention monitoring systems.
In Section 3Section 4 and Section 5the main algorithms for How to keep a great erection, visual and cognitive distraction detection are reviewed, respectively. Additionally, in Pregnant with the flu 6there are some algorithms detecting mixed types of distraction and, hence, are also reviewed. The relationship between facial expressions and distraction is also explored in Section 7.
The key points for the development and implementation of sensors to carry out the detection of distraction will be considered in Section 8. In Section 9the key ones to test and train driving monitoring systems are summarized. Privacy issues related to camera sensors are commented Kathy bates tits Section Lastly, conclusions, future aspects and challenges ahead will be considered in Section With the objective of introducing the scope and limitations of this review, some key aspects have been briefly introduced as follows.
Driver distraction is just one form of inattention, which Mom teaches daughter how to masturbate when drivers divert their attention away from the driving task to focus on another activity. At least, the system should detect both distraction and drowsiness as the main contributing factors in crashes and near-crashes.
As stated before, in this work, only distraction algorithms are summarized but one must not forget that other forms of inattention should be taken into account. However, these systems should not be treated like different alternatives, because they can be used together fusioned in order to obtain indicators for monitoring [ 22 ]. One of the challenges in decreasing the prevalence of distracted drivers is that many of them report that they believe they can drive safely while distracted [ 23 ].
However, for example, in connection with the use of mobile phones while driving, there is a great deal of evidence interacting with mobile devices, such as sending messages or engaging in conversations, which can impair driving performance because this interaction can create distraction.
Another study suggests that people in general can reduce both inattention Black sexy women in costomes hyperactivity symptoms simply by silencing the smartphones and avoiding notifications [ 25 ].
Therefore, it is clear that drivers should not use and notice the presence of the smartphones inside the car while driving. It should be pointed out that distraction generation is a very complex process and is scarcely addressed here.
We recommend some research papers that focused on driver distraction generation: Angell et al. In the context of intelligent vehicles, Ohn et al. Both distraction and inattention have been Wickedly lovely by melissa marr defined and the relationship between them remains unclear [ 30 ].
The use of different, and sometimes inconsistent, definitions of driver distraction can create a number of problems Sex city dior newsprint dress researchers and road safety professionals [ 31 ].
Inconsistent definitions across studies can make the comparison of research findings difficult or impossible, Pep boob show also lead to different interpretations of crash data and, therefore, to conclude different estimates of the role of distraction in crashes. This problem can be further seen in these recent works [ 32333435 ].
Many definitions have been proposed in order to define distraction [ 57831 ]. Regan et al. It is acknowledged that the taxonomy proposed by Reagan et al.
Driving consists of a variety of sub-tasks and it may not be possible to attend to all at the same time. Additionally, the dynamics of distraction [ 37 ], which identifies breakdowns on interruption as an important contributor to distraction should also be considered as part of this taxonomy, and hence, timing and context have implications on the algorithm design that should be taken into account. Papers addressed in this review are within the topic of distraction detection using vision-based systems.
The search and review strategy is described below. A comprehensive review of the English language scientific literature was performed. It encompassed the period from 1 January to 31 August Search terms related to driver distraction were employed combining all of them: driver, visual, cognitive, manual, biomechanicall, vision, vision-based, impairment, distraction, distractions, review, task, tasks, inattention, performance, phone, sms, vehicle, problem, looking, face, head, pose, glasses, illumination, self-driving, tracking, sensors, image, traffic, safety, facts, privacy, issues, porting, taxonomy.
Many items were returned from the search criteria shown before. These were, then, reviewed using the following criteria. Exclusion criteria were obviously Girls with menstruation papers or from medical, electronic, networking, marketing and patent topics. Only publications from peer-reviewed English language journals were considered for inclusion. Additionally, reviewed papers were ordered by the number of references in order to include all relevant papers.
Finally, in order to get the latest published papers, search filters were applied for this purpose. Search filters were applied to get publications only from years and References and bibliographies from the selected papers identified were examined to determine potentially additional papers. A total of approximately publications were revised in the review process. A common face processing scheme in many inattention monitoring systems, which can be seen in Figure 2includes the following steps:.
Face detection and head tracking. In many cases a face detection algorithm is used as a face tracking one. When the tracking is lost, a face detection call is usually involved that is why in Figure 2 Drivers webcam dk vision nocturna steps are placed inside the same external Drivers webcam dk vision nocturna box. Localization of facial features e. Facial landmarks localization is usually performed, but it should be noted that, in some cases, no specific landmarks are localized.
So, in such cases, estimation of specific cues are extracted based on anthropometric measures from both face and head. Viola-Jones [ 38 ] Ebonny blowjobs made object detection practically feasible in real world applications, which contains three main ideas that make possible to build and run in real time: the integral image, classifier learning with AdaBoost, and the attentional cascade structure [ 39 ].
This framework is used to create state-of-the-art detectors e. However, this framework turned out to Drivers webcam dk vision nocturna really time-consuming [ 41 ]. One possible solution is to use the standard approach for human detection [ 42 ], which can also be used for face detection [ 39 ]. This approach is based on the Histogram of Oriented Gradients HOGwhich is a feature descriptor used in computer vision and image processing for the purpose of object detection.
This approach can be trained with less images and faster [ 43 ]. Deep Learning approaches can also be used for face detection. Experiments were carried out on four publicly available unconstrained face detection datasets, which demonstrated the effectiveness of the approach. Consequently, complex features may provide better discrimination power than Haar-like features for the face detection task. However, they generally increase the computational cost [ 44 ].
Some modifications to the Viola-Jones algorithm have been proposed [ 4546 ] to speed up the algorithm. For example, in [ 45 ], different optimization techniques to speed up the Viola-Jones detector for embedded smart camera applications have been discussed.
In their paper, skin colour information is integrated with the Viola-Jones detector in order to reduce the computation time. PICO Pixel Intensity Comparison-based Object detection is another modification of the standard Viola-Jones object detection framework, which scans the image with a cascade of binary classifiers at all reasonable positions and scales [ 46 ]. This is especially evident on devices with limited hardware support for floating point operations.
For example, learning-based methods e. Position of the camera inside the car is another key factor in the detection rate.
Therefore, if the camera is installed on the dashboard, the captured images will contain frontal or near-frontal faces. In Latex table column 49 ], the camera was placed over the steering wheel column for two Drivers webcam dk vision nocturna a it facilitates the estimation of gaze angles, such as pitch, which is relevant for detecting distraction, and b from a production point of view, it is convenient to integrate a camera into the dashboard.
On the downside, when the wheel is turning, there will be some frames in which the drivers face may be occluded by the steering wheel. However, the driver is seldom very sleepy or inattentive to traffic while turning Drivers webcam dk vision nocturna steering wheel.
Axial rotation, i. Lateral bending, i. Hence, a key component for a monitoring system based on face tracking is the ability to robustly and continuously operate even during large head movements. However, face tracking remains a challenging vision problem and, hence, a system for a continuous estimation of head movement is needed.
On the other Miley cyrus foot lovers, as many head tracking algorithms have shown good performance when the head is near frontal, it can be concluded that the driver is looking away when tracking is unavailable.
Accordingly, numerous research works and publications have been trying to perform face tracking using a single camera and they are discussed as follows.
