- Adaptive contrast enhancement (ACE) adjusts image contrast by giving more contrast to areas which are originally low in contrast. This is different from histogram-based techniques which are based on all image pixels (the histogram itself).
- Local histogram equalization is another technique that can be used to reveal detail of areas, since it depends on area pixels only. Use LocalHistogramEqualizeCommand to perform a local histogram equalization.
- This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
- This command does not support 32-bit grayscale images.
