发明名称 Enhanced image compression utilizing Hilbert curve scanning of quantized discrete cosine transform coefficients
摘要 A method for compressing images, the method including the steps of partitioning image information for an image into partitioned information, transforming the partitioned information into transformed information using a discrete cosine transform ("DCT"), and quantizing the transformed information into quantized information. The method further includes the steps of sequencing the quantized information into sequenced information using a Hilbert curve scan, encoding the sequenced information into encoded information, and storing the encoded information. The DCT is a JPEG DCT.
