Abstract

Image compressor in aerospace application is susceptible to single event effect, causing encoder logic errors and system errors. Therefore, the image compressor in aerospace application must be specially designed to improve the reliability of image information. Compression efficiency of JPEG-LS is higher than JPEG2000 and compression effect is better than lossless JPEG. Especially, JPEG-LS algorithm has the characteristics of low complexity and easy hardware implementation, which will save hardware resources of spaceborne system. An image compressor based on lossless JPEG-LS algorithm is designed in this paper, which can correctly compress 512×512 8-bit wide grayscale images. It is hardened by three-mode redundancy, Hamming code, timeout detection, one-hot code, and inter-process independently. The results point out that the error rate caused by SEU is significantly reduced 19.48% using the hardened compressor in this paper.

基于无损JPEG-LS的抗辐射图像压缩器设计

航天应用中的图像压缩器容易受到单事件效应的影响，导致编码器逻辑误差和系统误差。因此，在航空航天应用中，必须对图像压缩器进行专门设计，以提高图像信息的可靠性。JPEG- ls的压缩效率高于JPEG2000，压缩效果优于无损JPEG。特别是JPEG-LS算法具有复杂度低、易于硬件实现的特点，将节省星载系统的硬件资源。本文设计了一种基于无损JPEG-LS算法的图像压缩器，能够正确压缩512×512 8位宽灰度图像。它通过三模式冗余、汉明码、超时检测、单热码和进程间独立进行加固。结果表明，采用淬硬压缩机后，由单轴流引起的错误率显著降低了19.48%。
