摘要
A method for compression and decompression of image data. The data is received as an initial image at an encoder. The encoder compresses the data by performing a spatial frequency decomposition on the image data, modifying selected frequency band images produced by the decomposition by applying a non-linear transformation, quantizing the results and compressing them into a bit stream. The data is then transmitted to a decoder that reverses the process.
