Generating shadows from a segmentation mask

Abstract

Disclosed herein are system, method, and computer program product embodiments for generating realistic shadows for an image object, such as a vehicle, for computer browsing. The method includes generating a segmentation of an image object; generating a contour from the segmentation mask, wherein the contour comprises an array of the pixels along a boundary of the segmentation mask; calculating a plurality of regions of the contour, wherein each of the plurality of regions comprise a set of continuous points; identifying within the plurality of the regions of the contour, a plurality of key points that correspond to ground contact points of the image object; applying, based on the plurality of key points, a perspective warping to a first shadow template to generate the shadow for the image object, and rendering, on a selected background, the image segmentation as an overlay on the shadow.
