@Shushruth: This function can directly deal with any grayscale intensity image of form uint8, uint16, int16, single, double. For color images you can just process the intensity plane as exemplified above. As for BW/Binary image, any contrast enhancement does not introduce any change since there are only 2 gray levels, and changing contrast would imply, making either the whole image black/white.

You need to do the spell check. The correction to the help file has been reflected and will be up soon. Call using 'triangular' and not 'traingular'.

@ismaiel. I believe your query is not related to this particular submission. I hope you do not mind dropping me a few lines on my email elaborating your requirement, and I would try to see on possibilities of helping you.

Using BPDFHE for Color images can be done accordingly

rgbInputImage = imread('peppers.png');
labInputImage = applycform(rgbInputImage,makecform('srgb2lab'));
Lbpdfhe = fcnBPDFHE(labInputImage(:,:,1));
labOutputImage = cat(3,Lbpdfhe,labInputImage(:,:,2),labInputImage(:,:,3));
rgbOutputImage = applycform(labOutputImage,makecform('lab2srgb'));

Details of the technique for implementing BPDFHE on color images is detailed in

The transformation map returned by the function has the following characteristics.

UINT8 image - 256 element array mapping 0-255 grayscale intensities

UINT16 image - 65536 element array mapping 0-65535 grayscale intensities

INT16 image - 65536 element array mapping -32768:32767 grayscale intensities

SINGLE/DOUBLE type image - 256 element array mapping grayscale intensities in range I_min:I_max, where I_min and I_max are the minimum and maximum intensity in the input image

Works nicely, though minor enhancement achieved in my case :(
