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.
Claims8
A method comprising:
- 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.
A software product tangibly stored on a computer-readable medium, the software product comprising instructions operable to cause a programmable processor to perform operations comprising:
- 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.
An apparatus comprising:
- means for receiving an image;
- means for displaying the image;
- and means for combining a first image region and a second image region to form a blended image region including a neighborhood mean and a neighborhood variance that are linear blends of the first and second image regions using a common blending parameter.
A system comprising:
- a data storage system;
- at least one input device;
- at least one output device;
- and at least one programmable processor coupled to receive information from, and to transmit information to, the data storage system, the at least one input device, and the at least one output device;
- wherein the data storage, system includes a machine-readable medium tangibly embodying a software product comprising instructions operable to cause the at least one programmable processor to perform operations comprising 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.
