Chapter 8: High-Pass Filters and Feature Detection
In the previous chapter, we learned about kernels and low-pass filters and their applications. We learned about and demonstrated how to use low-pass filters in blurring, smoothing, and de-noising images.
In this chapter, we will learn about and demonstrate the uses of high-pass filters. This includes their application in image processing and computer vision. First, we will explore the Laplacian, Scharr, and Sobel high-pass filters. Then, we will learn about the Canny edge detection algorithm. We will also demonstrate Hough transforms for circles and lines. We will conclude by looking at corner detection with the Harris algorithm.
The following is a list of the topics we will cover in this chapter: ...
