Abstract

A vehicle is equipped with a camera (which may be a stereoscopic camera) and a computer for processing the image data acquired by the camera. The image acquired by the camera is processed by the computer, and features are extracted therefrom. The features are further processed by various techniques such as object detection/segmentation and object tracking/classification. The acquired images are sometimes contaminated by optical occlusions such as raindrops, stone-chippings and dirt on the windshield. In such a case, the occluded parts of the image are reconstructed by optical flow estimation or stereo disparity estimation. The fully reconstructed image is then used for intended applications.
