Image Processing
This example of compute shaders uses them as a means to implement image processing algorithms. In this case, we implement a simple edge-detection algorithm by convolving an input image with an edge-detection filter. The filter chosen is an example of a separable filter. A separable filter is one that can be applied one dimension at a time in a multidimensional space to produce a final result. Here, it is is applied to a two-dimensional image by applying it first in the horizontal dimension and then again in the vertical dimension. The actual kernel is a central difference kernel [–1 0 1].
To implement this kernel, each invocation of the compute shader produces a single pixel in the output image. It must read from the input image ...
