Brazilian scientists were able to develop an algorithm for the recognition of phone conversations while driving using the camera built into the dashboard of the car. The developers claim that the incrimination driver to use the phone while driving is sufficient to analyze a video no longer than three seconds with a resolution of 320 x 240 pixels and a refresh rate of 15 frames per second. Under these conditions, a special three-step algorithm gives the correct result in 87.43% of cases.
The algorithm is based on the method of determining the position of the hands relative to the driver's face. As a rule, in the interior of the car driver's face is a contrasting subject, which can be easily separated from the crowd. Hands in the frame the camera is also able to easily notice. However, there is disadvantages. For example, under the bright sunlight, it loses its effectiveness, and the man in gloves has a chance to remain unpunished. Related Products :
