摘要： An example-based facial sketch system and process that automatically generates a sketch from an input image depicting a person's face. Sketch generation is accomplished by first training the system using example facial images and sketches of the depicted faces drawn with a particular style by a sketch artist. The trained system is then used to automatically generate a facial sketch that simulates the artist's style from an input image depicting a person's face. Nonparametric sampling and a flexible sketch model are employed to capture the complex statistical characteristics between an image and its sketch.

摘要： The present invention involves a new system and method for synthesizing textures from an input sample. A system and method according to the present invention uses a unique accelerated patch-based sampling system to synthesize high-quality textures in real-time using a small input texture sample. The patch-based sampling system of the present invention works well for a wide variety of textures ranging from regular to stochastic. Potential feature mismatches across patch boundaries are avoided by sampling patches according to a non-parametric estimation of the local conditional Markov Random Field (MRF) density function.
