Latest Patents

Among his latest patents is a groundbreaking invention pertaining to frame buffer compression for video processing devices. This patent outlines a method for compressing a video signal by applying a local multiscale transform to video frames, resulting in coefficient blocks. These coefficients are then grouped, and for at least one group, a common exponent is determined to aid in encoding the coefficients. The mantissas are quantified in conjunction with this common exponent and stored as coding data in an external frame buffer, which is vital for efficient video processing.

Another noteworthy patent developed by Mallat is related to a multiscale modulus filter bank, which has applications in pattern detection, clustering, classification, and registration. The patent describes a digital filter bank with multiple stages, where each filtering unit performs low-pass and band-pass filtering. The processed signals are generated through modulus processing of the complex output values, showcasing Mallat's innovation in enhancing signal analysis methodologies.
