Parameters

sourceImage

Pointer to the source image/ROI.

histogram

Pointer to the destination vector.

region

Pointer to a region to apply the function only on a particular region in the image.

mostSignificantBit

Index of the most significant bit of the pixels (0 has weight 1).

numberOfSignificantBits

Number of significant bits; the histogram will possess 2^{numberOfSignificantBits} entries.

saturate

Boolean indicating if values larger than 2^{mostSignificantBit}-1 are saturated (default true) or not (false).

mask

Pointer to a mask to apply the function only on a particular region in the image. Note: the mask must have the same size as the source image.
