Chapter 1. Applying Effects to Images

Generally, an image contains more information than required for any particular task. For this reason, we need to preprocess the images so that they contain only as much information as required for the application, thereby reducing the computing time needed.

In this chapter, we will learn about the different preprocessing operations, which are as follows:

  • Blurring
  • De-noising
  • Sharpening
  • Erosion and dilation
  • Thresholding and adaptive thresholding

At the end of this chapter, we will see how you can integrate OpenCV into your existing Android applications.

Before we take a look at the various feature detection algorithms and their implementations, let's first build a basic Android application to which we will keep adding feature detection algorithms, as we go through this chapter.
