  • Edit propagation on raster sketches
    Patent number: 10832454
    Abstract: A method, apparatus and system provides the ability to edit a raster sketch. An edit gesture is received and a binary image of the raster sketch is calculated by thresholding. A stroke width transform (SWT) map is calculated and stores a stroke width value for each pixel. An original outside contour of the binary image is calculated and simplified. A propagation cut is determined as a line segment that connects two different points on the simplified contour that separates the simplified outside contour into two parts. The propagation cut is applied to the original outside contour and displayed.
