How to optimize medianBlur using parallel_for? [closed]

asked 2014-10-15 04:07:16 -0500

Hello folks. I am trying to optimize median filter and morphological operations using openCV for ARM device. I've finished it using SIMD processing and NEON. But when image is high-quality, optimizing performance is reduced. So i decided to use the parallel computing technology. But I don't know where I start. How i can solve my problem and what i can use for parallel computing. Thank's

Maybe this topic can start guiding you to using the parallel for loop.

Can you share how did u write median blur using SIMD and NEON. I m using 5X5 opencv median blur and its taking a lot of time. I want to optimise it. Image size id approximately 640X640 / 640X480
