Paper Abstract

Satellite remote sensing image compression system is expected high compressing rate, real time dealing and high fidelity. Based on lapped biorthogonal transform (LBT) and its integer algorithm, this paper describes a fixed-point lapped transform algorithm using approximation to trigonometric function, studies the structure of LBT coefficients and presents a modified zerotree coding algorithm. Also, this paper studies the implementation in TMS320C6000 DSP of the algorithm, the processing speed is improved through task combining, complier options, software pipelining, loop unrolling and complex instruction. This algorithm has been used in a prototype of data compression equipment. Image coding experiments show that the algorithm's memory requirement is low and its coding performance is very competitive with SPIHT when its complexity is far lower than SHIHT.
