Image Statistics (histogram) mask #176

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
Describe the feature you are interested and which may bring benefit to the
project ...

It consists in being able to perform the image statistics estimation 
(ImageStatistics, ImageStatisticsHSL, and ImageStatisticsYCbCr) based not only 
on a rectangular image, but using an area/blob mask, so to estimate statistics 
for a blob, etc. They provide a "withoutBlack" option, which is not suitable 
when the blob/area has internal black spots.

Provide any references/links to publications/algorithms/etc. which could
help in development ...

OpenCV libraries provide such functionality in its histogram estimation 
procedures (among others). AForge uses masks in some functionalities too.

Updated ImageStatistics, ImageStatisticsHSL and ImageStatisticsYCbCr classes so 
they can gather statistics over image area, which can be specified with a mask 
(8bpp image or byte[,] array).

Committed in revision 1473. Will be released in version 2.2.0.
