: The finite elements of a digital image, also called "picture elements". Image Types : Common types include (black and white), gray-scale (0–255 intensity levels), (RGB/HSI), and multispectral Digitization : To process a continuous image digitally, it must undergo: : Digitizing the coordinate values ( Quantization : Digitizing the amplitude (intensity) values. Fundamental Steps in the DIP Workflow Modern image processing typically follows these key stages:

The Fast Fourier Transform (FFT) algorithm reduces complexity from (O(N^4)) to (O(N^2 \log N)). digital image processing notes

Wavelets and Multi-resolution Processing: This area focuses on representing images at various degrees of resolution. Wavelets are used to decompose an image into different frequency components, which is particularly useful for image compression and feature extraction. : The finite elements of a digital image,
