Now that we have looked at the basic image processing techniques using the Scikit Image library, we can move on to its more advanced aspects. In this chapter, we use one of the most comprehensive computer vision libraries: OpenCV and examine the following concepts:

Blending two images
Changing the contrast and brightness of an image
Adding text to images
Smoothing images
Changing the shape of images
Effecting image thresholding
Calculating gradients to detect edges
Performing histogram equalization

Blending Two Images
