Unlike enhancement, which is subjective, image restoration aims to reconstruct an image that has been degraded by a known process.

Using local processing or global processing via the Hough Transform to detect geometric shapes like lines and circles. Thresholding: Global thresholding for high-contrast images. Adaptive/Local thresholding for non-uniform illumination. Otsu’s Optimum Thresholding method.

Primarily used in compression.

). Types include 4-adjacency, 8-adjacency, and m-adjacency (mixed adjacency to eliminate multi-path ambiguity). : Euclidean Distance, City-Block ( D4cap D sub 4 ) Distance, and Chessboard ( D8cap D sub 8 ) Distance. 3. Image Enhancement in the Spatial Domain digital image processing jayaraman ppt

Image enhancement aims to improve visual appearance or emphasize features for interpretation. Spatial domain methods operate directly on pixels and include contrast stretching, histogram equalization, smoothing filters (mean, median) for noise reduction, and sharpening filters (Laplacian, unsharp masking) to emphasize edges. Frequency domain methods transform images (typically via the Fourier transform) and manipulate spectral components—low-pass filtering for blur, high-pass for edge enhancement, and band-pass for texture emphasis. Adaptive techniques adjust processing based on local image statistics. smoothing filters (mean

Intensity resolution is determined by quantization bits (e.g., 8-bit image has 256 gray levels). Essential Formula for Slides Total number of bits required to store a digital image: B=M×N×kcap B equals cap M cross cap N cross k Chapter 3: Image Enhancement in the Spatial Domain

Why? Because S. Jayaraman’s book (often co-authored by Esakkirajan and Veerakumar) is considered the . It bridges the gap between complex mathematical theories (like Fourier transforms and Wavelets) and practical exam-oriented problem-solving.
