Abstract: A method for enabling a user to paint an image uploaded to a device is provided. The method includes uploading an image to the device, performing a depth estimation on the image to generate a depth map, and performing an edge detection on the image to generate a first edge map. The method also includes performing the edge detection on the depth map to generate a second edge map, performing a skeletonization function on the first edge map to generate a third edge map, and performing the skeletonization function on the depth map to generate a fourth edge map. The method also includes generating a final edge map using the third edge map and the fourth edge map, generating a colorized image by applying color to the final edge map to paint at least one wall of a scene, and displaying the colorized image on a display of the device.
