“…in the field of developing autonomous driving cars computer vision has become a key component, due the advances in visual environment perception like object classification, detection, segmentation and distance estimation Techniques .Researchers mainly focus on object classification, detection and segmentation [1,2,3], beside a lot of efforts on improving the accuracy of visual perception crucial information for cars to avoid collisions, adjust its speed for safety driving can be provided through distances estimating between camera sensors [25,26,27] and recognized objects (e.g. cyclists , pedestrians ,cars) and not only by recognizing the objects on the way.…”
