The attached C++ project uses LEADTOOLS v17.5 C DLL programming interface to load two images, then you can compare between the brightness (Intensity) and Saturation between both images to see which is brighter and which has more saturation.
The main idea behind this project is:
First part: Brightness, check the histogram of image (1) to calculate the average intensity value (int1), then do the same for image (2) and calculate its intensity (int2).
Comparing these 2 numbers should give you a measure of which has more intensity (brighter).

Second part: Saturation, Separate the colors as HSV planes for image (1), then extract the Saturation's histogram of image (1) to calculate an average saturation value (sat1), then do the same for image (2) to calculate sat2.
Comparing these 2 numbers should give you a measure of which has more saturation average.

Updated to LEADTOOLS v19 with Visual Studio 2017. Changed to Visual Studio 2010 (v100) Platform Toolset.
Extract to "C:\LEADTOOLS 19\Examples\CDLL\" to use the example.

Note: The program doesn't display the images, it has menu options to compare the two images for intensity or saturation.
