3.2.6 Canny Edge Detection
The Canny edge detector is an edge detection operator that uses a multi-stage
algorithm to detect a wide range of edges in images. Sobel Edge Detection is used to
compare with Canny Edge Detection but the performance of Sobel Edge detection is
poorer than Canny Edge Detection in this project. Table 3.4 shows the comparison
between canny edge detection and sobel edge detection.
