Improved contours for ToF cameras based on vicinity logic operations

In this article we propose an improved contour extraction approach for images acquired with a Time of Flight camera (ToF), by combining the information from the edges of the distance and luminance images. We define and use vicinity logic operations in order to extract a better contour that allows us to emphasize the objects of interest in the scene, and in the same time to eliminate the unuseful information, i.e. the “false” contours determined by noise, various textures, shadows etc. We present our results and draw the conclusions.
