Gabor Filter

A Gabor filter is a mathematical tool used in image processing to analyze textures and patterns. Think of it like a specialized window that focuses on specific edges, lines, or repetitive patterns within an image, highlighting details at particular scales and orientations. It combines a sine wave (to detect frequency) with a Gaussian shape (to focus on a local area), allowing it to effectively identify features like textures or edges similar to how our visual system processes visual information. Gabor filters are widely used in applications like facial recognition and texture analysis.
