Wavelet noise is a better alternative to Perlin noise for creating natural-looking textures in 3D graphics. It overcomes problems such as loss of detail and aliasing, and allows for finer control over the shape of the spectrum. Developed by Tony DeRose and Robert L. Cook at Pixar Animation Studios, it is optimally band-limited and allows […]
Wavelet compression is a technique used to compress audio and video signals, which works best for high-contrast images and short audio. It uses wavelet transformations to gather information about the file, which can result in a lossless or lossy compressed file. The process involves treating the image as a series of wavelets, measuring pixel coefficients, […]
