Producing automatic “painting” effects in images
View Patent ↗Method is disclosed for the automatic creation of images in a “van Gogh” style. The method comprises locating portions of detail in an image an utilizing the area of detail to propagate brush strokes into areas of the image having lesser details. A number of modifications are also proposed including utilizing refining brush strokes to process those areas of detail in an image.
1. A method of automatically processing an image comprising the steps of:
locating, within the image, features having a high spatial variance by thresholding and skeletonising the image to produce an image comprising single pixel width definition of features;
discard features of the produced image having a size less than a predetermined size;
fitting curves to the remaining features; and
stroking the image with a series of brush strokes emanating from said remaining features of the produced image in accordance with the fitted curves.
2. A method as claimed in claim 1 wherein said brush stroke have decreasing sizes near important features of the image.
3. A method as claimed in claim 1 wherein said brush strokes include opacity and bump maps for added realism.
4. A method as claimed in claim 1 wherein the position of a predetermined portion of brush strokes undergoes random jittering.
5. The method of claim 1 wherein the step of discarding comprises discarding located features having a size of less than 20 contiguous pixels.
