We will continue from a previous example of RGBA to gray image conversion with CUDA 5 and add gaussian filter. After applying the filter we will achieve the following transformation: to: Here’s the information showing time it took to run CUDA kernel on the GPU compared to time on the CPU: This code will work with RGBA images where […]

In this article we will demonstrate a simple conversion from RGBA to grayscale image using CUDA 5, we will build on a previous example of a simple CUDA kernel. For example, the following RGB picture of flowers will look like this after running the filter: and to execute the application we will call it like […]
