Web22 de fev. de 2013 · This article presents Parallel implementation of Gaussian filter using OpenCL programming APIs.It has been tested on Intel (R) Core (TM) i3 CPU at 2.53GHz on Ubuntu 12.04 OS.The average run time analysis of parallel implemetation was compared with OpenCV algorithms and a performance improvement of 3x-4x was observed. WebIn image processing, a convolution kernel is a 2D matrix that is used to filter images. Also known as a convolution matrix, a convolution kernel is typically a square, MxN matrix, where both M and N are odd integers (e.g. 3×3, 5×5, 7×7 etc.). See the 3×3 example matrix given below.
