Impact Acquire SDK GUI Applications
Pixel Histogram

The pixel histogram control does provide a way to visualize the intensity distribution of the individual color channels of an image:

ImpactControlCenter - Pixel Histogram

In this example as the AOI contains a lot of green pixels, less red pixels and even less blue pixels of different medium intensities the resulting histogram has peaks within the middle of the histogram where the green peaks are the highest, followed by red and then blue.

The displayed analysis results in the graphical view will be scaled automatically to accommodate the most frequent value. At the top additional information about each color channel will be displayed. From left to right the 3 values per channel are

  • the mean/average value
  • the most frequent value count
  • the most frequent value
