Hi,
I am trying to implement Contrast Limited Adaptive Historgram Equalization an image using the command adapthisteq(I) but i am getting error like
"Error using adapthisteq
Expected input number 1, I, to be two-dimensional."
I have attached my image here, can anyone pls guide me the problem with it.
Note: since the file format of tif is not supported in the attachment, therefore i am attaching jpg format of my file.
Thanks

Thanks Stephan,
I also think that the issue is of dimensions, when i have converted the image into Gray image. there was no error and i was able to apply the CLAHE.

Before calling adapthisteq(), cast the image to gray level if it's not already:
if ndims(I) == 3
I = rgb2gray(I)
end
