Image processing to detect edges, walls, and surfaces for a virtual painting application

Abstract

Systems and methods are provided an include generating a depth map by performing depth estimation on an image having at least one wall, generating a first edge map that includes a first set of edge lines outlining the at least one wall by performing edge detection on the image, generating a second edge map that includes a second set of edge lines by performing edge detection on the depth map, generating a third edge map by thinning a width of each edge line in the first set of edge lines, generating a fourth edge map by performing a skeletonization function on the depth map, generating a final edge map based on the third edge map and the fourth edge map, generating a colorized image by applying color to the final edge map to paint the at least one wall, and displaying the colorized image on a display.
