Non-photo-realistic rendering (NPR) refers to any technique which can produce a non-photo-realistic image. We present a method for automatically generating a stroke-based painting from a digital image. The rendering process generates rectangular brush strokes with suitable location, orientation and size. Inspired by the real painting process, where a painter always observes the distinctive features and decides the shape and orientation of the stroke, we apply techniques of image moment functions and texture analysis, from which features are extracted and used to guide the stroke generation. Techniques are also developed for dynamic determination of cropped image size and edge enhancement. The main features in the source image are well preserved.
