This chapter has covered the most common image processing methods used in computer vision. Image processing is often the step performed just before further computer vision applications. It has many methods and is usually applied for image corrections and enhancement such as image histograms, image equalization, brightness and contrast modeling, image color conversion by means of histogram matching and color space transformations, filtering using the model of the human retina, and arithmetic and geometrical transforms.

The next chapter will cover the next stage in a computer vision system, that is, the segmentation process. We will see how to extract regions of interest within an image.
