Latest Patents

Jiang holds a patent for a "Method and apparatus for extracting pixel values." This innovative method utilizes a forward discrete cosine transform (DCT) to extract luminance and chrominance values from pixels encoded in MPEG or JPEG formats. By analyzing the forward DCT used in MPEG encoding, he derived equations that relate pixel values to DCT coefficients. This allows for rapid and computationally efficient extraction of pixel values directly from the DCT coefficients, eliminating the need for an inverse DCT transform. His approach enables the fast extraction of original images from MPEG and JPEG encoded versions.
