Chapter 7. Performing Image Processing Techniques
In this chapter, we will use compute shaders (or DirectCompute) for the following image processing techniques:
- Running a compute shader – desaturation (grayscale)
- Adjusting the contrast and brightness
- Implementing box blur using separable convolution filters
- Implementing a Gaussian blur filter
- Detecting edges with the Sobel edge-detection filter
- Calculating an image's luminance histogram
Introduction
Image processing is the process of applying a signal-processing technique against an input image. The input image is generally a two-dimensional signal with the output being either another image or any properties derived from the input signal.
During this chapter, we will implement a number of filtering techniques ...
