• Spatial Domain Methods: These operate directly on the image pixels. Point processing techniques, such as contrast stretching and histogram equalization, are fundamental. Histogram equalization, for instance, redistributes intensity values to achieve a uniform histogram, thereby enhancing global contrast. This is a classic example of how a simple mathematical transformation can dramatically improve visual interpretability.
• Frequency Domain Methods: These techniques rely on the Fourier Transform. By transforming an image into the frequency domain, one can manipulate specific frequency components. High-pass filters sharpen edges, while low-pass filters smooth noise. The transition from the spatial domain to the frequency domain is a complex theoretical hurdle for students; however, the pedagogical use of step-by-step mathematical derivations, as found in Sridhar’s text, elucidates the underlying physics of wave propagation and signal filtering.
