Color dithering is a technique used in computer graphics and multimedia to simulate a wider range of colors than are actually available in a given color palette or display system. It works by arranging pixels of available colors in specific patterns so that...

A digital image is represented by a matrix (2D array) of numeric values, where each value represents a quantized intensity value at a specific location in the image. If I is a two-dimensional matrix, then I(r, c) denotes the intensity value at row r and col...

Image format is defined by how image data is captured, stored, and represented digitally. It can be of two types: The image format is specified by two main parameters: - Spatial Resolution: specified as pixels (e.g., 320 x 240 pixels) - Color Encoding: spec...
