Hello,

I have an Image - `mA` which I divided into Blocks: `mA1`,`mA2`, `mA3`, `mA4`.

Now I have a function - `BlurImage` I want to operate on each:

mB1 = BlurImage(mA1);

mB2 = BlurImage(mA1);

mB3 = BlurImage(mA1);

mB4 = BlurImage(mA1);

Is there a way to run those 4 operations in parallel in MATLAB?

I want to process sub sections of the image in parallel and I want to make it as efficient as possible (And better yet, using the same strategy I later can use in C with OpenMP).

Thank You.

Hi Royi Avital, The BLOCKPROC function from the Image Processing Toolbox processes the images by applying the function to each distinct block of the image. Please refer to the documentation link at: http://www.mathworks.com/help/images/ref/blockproc.html to understand how to use the function. There is an option 'UseParallel' for this command, which when set to 'true',blockproc will attempt to run in parallel mode if you have Parallel Computing Toolbox.
