Image coding embedded in matrix operation

摘要

An image coding embedded in matrix operation. A sorting and refining processes are merged, based on matrix and the stream control mechanism, a novel concept for embedded image compression in a single stage is achieved. A significant map array is used to determine whether the node in a hierarchic tree is significant to ensure and enhance the compression efficiency. A status bit coding processing apparatus employing the above method is based on a simple algorithm logic to require only one and a quarter memory space of an image transform coefficient. The design of the bit budget controller further overcome the conflict between the embedded type and matrix type coding to ensure a high efficient compression well suited for the implementation of low cost hardware chip or DSP chip.
