Is it possible to use GPU acceleration on deconvlucy

Hi,

Im trying to sharpen images using deconvlucy. I'm wondering if it is possible to use the GPU to accelerate this?

I tried with the code below, but it does not work.

image = gpuArray(imread('peppers.png'));
%Convert the image to doubles, and apply convolutions to obtain the gradient image. Then, using the gradient image, sharpen the image by a factor of amount.
dimage = im2double(image); 
PSF = fspecial('gaussian',7,10);
gradient=deconvlucy(dimage, PSF);

'deconvlucy' function doesn not support GPU acceleration. You can refer to this documentation to find out whether a MATLAB function supports GPU acceleration or not.

Thanks for the answer. I looked inside the matlab code for the deconvlucy. Do you think it would be possible to convert the code to use gpuArray etc? So basically convert it to being gpu accelerated. The other alterntive would be to write the whole code in OpenCL which seems like a very challenging task.

Thanks!

By convert it, I assume you mean, make a modified copy of it.

Hi! Yes what Im considering is copy the matlab script and change it so that it uses gpuArrays etc. Im just wondering if there may be some limitations that Im not aware of. Im still quite new to the parallel toolbox. Thanks!
