Thresholding creates binary images from grayscale data based on intensity limits. % Canny edge detection edges = edge(grayImg, 'canny');

Point operations modify individual pixels based solely on their current value. A primary tool for analyzing these values is the histogram. title('Canny Edge Detection')

Perform operations using the Fourier Transform ( fft2 ) to filter specific frequencies, useful for periodic noise removal. 2. Geometric Transformations

The edge() function, particularly with the 'Canny' method, offers superior edge detection capabilities. Morphological Operations
