Later strokes cover earlier strokes, and strokes painted at a similar time are likely to be part of the same object. In the final painting, this temporal history is lost, and a static arrangement of color is all that remains. The rich literature for(More)
My research interests are image & video processing, computer graphics, and computer vision. Currently, I am focusing on decomposing images or time-lapse painting videos into translucent layers, to make image reediting much easier. More generally, I am interested in the application of geometry of color spaces and image edits. Given an image, either(More)

Artwork c Adelle Chudleigh. Abstract In digital painting software, layers organize paintings. However, layers are not(More)
