Latest Patents

Among his latest patents, Peng Gao has developed a method for limited error raster compression. This invention relates to an image or raster compression method for a multi-dimensional array of pixels. A user specifies a maximum error allowable per pixel for the compression algorithm. The raster is divided into a number of pixel blocks where each pixel is quantized and bit stuffed based on various block statistics, including the maximum error allowable. The size of the pixel blocks is limited to two, such as 8×8 and 16×16, to save processing time with minimal difference in compression. Additionally, a Look-Up Table (LUT) is utilized for certain types of data where it proves to be more efficient.

Another patent by Peng Gao focuses on a similar limited error raster compression method. This method includes receiving pixel data for a raster comprising a two-dimensional (2D) array of pixels, where each pixel is associated with a data value. The method further involves receiving a user-defined parameter that defines a maximum error allowable per pixel for a compression algorithm. The raster can be divided into pixel blocks, allowing each pixel to be quantized and bit stuffed based on block statistics, including the maximum error allowable. The compression algorithm is executed such that for each pixel, the error caused by the compression is equal to or less than the maximum error allowable, encoding the pixel data based on the algorithm.
