Rendering of photorealistic computer graphics images

摘要

A method, apparatus, and system are provided for rendering of photorealistic computer graphics images. According to one embod iment, an image is partitioned into regions, each of the regions having a discontinuity edge, a boundary, edge pixels along the boundary, and remaining pixels, and orientation of the discontinuity edge is estimated by computing a direction of least discrepancy within each of the regions by evaluating the edge pixels along the boundary of each of the regions.
