Latest Patents

Viresh Ratnakar holds a patent for an "Image compression system and method having optimized quantization tables." This invention provides a digital image compression preprocessor designed for use in a discrete cosine transform-based digital image compression device. The preprocessor includes a gathering mechanism that determines discrete cosine transform statistics from input digital image data. A computing mechanism is coupled to the gathering mechanism to calculate an image distortion array and a rate of image compression array based on the discrete cosine transform statistics for each possible quantization value. Furthermore, a dynamic programming mechanism optimizes the rate of image compression array against the image distortion array, resulting in a rate-distortion-optimal quantization table. This patent also encompasses a discrete cosine transform-based digital image compression device and a system for compression and decompression.
