ABSTRACT:
Systems and techniques for blending image data such that noise, texture and/or high-frequency data may be better preserved in a resulting blended image. In general, in one implementation, the techniques include combining a first image region and a second image region to form a blended image region having a neighborhood mean and a neighborhood variance, at each of multiple points in the blended image region, that are linear blends of corresponding neighborhood means and variances from the first and second image regions using a common blending parameter.
