Steerable wavelets

Steerable wavelets are a mathematical tool used in image analysis that can efficiently detect features like edges or textures at different orientations. They are designed so that, by adjusting certain parameters, you can "rotate" the wavelet to focus on features pointing in any direction without reconstructing from scratch. This flexibility allows for more precise analysis of complex patterns in images, such as identifying the orientation of structures in medical scans or satellite images. Essentially, steerable wavelets provide a powerful way to analyze the directionality of image features quickly and accurately.
