As of Open Inventor 2023.2. ImageViz API is replaced by the new ImageDev toolkit.

SoHistogramEqualizationProcessing engine. The SoHistogramEqualizationProcessing engine performs a histogram equalization.
This engine performs a histogram equalization of image I onto image O. For example, if an image contains n pixels and uses M gray values, there is an average of n/M pixels per gray level. An image is correctly contrasted if the number of pixels is closed to this mean value for each gray level value.
The aim of histogram equalization is to transform the histogram to make it uniform. In Figure a, the histogram is very condensed, and the image is poorly contrasted. In Figure b, the histogram is more widely distributed, and the image has a better contrast.
