Multi-resolution Analysis

Multi-resolution Analysis (MRA) is a method used in signal processing to analyze data at different levels of detail or scales. It allows us to break down a complex signal or image into various components, such as broad trends and fine details. Think of it like zooming in and out on a picture to see both the overall scene and the intricate features. This approach helps in tasks like noise reduction, feature detection, and data compression, by focusing on the most relevant information at each resolution level.
