hello, I'm trying to make my code (which is based on the detectMSERFeatures function and I call it a few times every frame) run faster and for that, I thought I should run it on a GPU. correct me if I'm wrong and if any of you have suggestions be my guest. thanks in advance :).

Why don't you inspect the function gpuArray/detectHarrisFeatures which is implemented in MATLAB code. It should give you a few ideas.
edit gpuArray/detectHarrisFeatures
With properly vectorized code there's often very little customisation needed. As you can see, detectHarrisFeatures shares most of its implementation with the CPU version.

if I'll use gpuArray all operations performed on the array would be done by the GPU? also what does "detectHarrisFeatures" has to do with "detectMSERFeatures"?

Yes. And ... well ... they're both types of image feature detection? I'll admit the underlying algorithms aren't the same but the point is to give you some examples of MATLAB code that run successfully and efficiently on the GPU, in an area you're familiar with (presumably).
