Abstract
Sketch and cartoon images are automatically generated from video or still images captured in real-time from a digital camera or obtained from a stored file. Steps of the method include calculating luma values for each pixel in a captured or retrieved image, applying noise reduction techniques to the captured or retrieved image to improve its quality, performing an adaptive luma chroma difference computation to find and mark edges of objects in a captured or retrieved image as lines forming objects in a sketch image, and applying noise reduction to the sketch image. The process may be repeated for each frame in a video sequence. Temporal smoothing is applied to the video sequence of frames. Generated sketch images may be colored to produce cartoon images.
