摘要
采用BP算法,根据评价指标建立遥感影像压缩质量等级评价模型,达到了利用客观质量测度参数实现主观质量评价的目的,并可动态改进模型,实验结果证明了该模型的有效性。
By BP feed-forword algorithm, it establishes the grade model for assessing the quality of remote sensing image compression based on guidelines. It achieves the aim at subjective assessment replaced by objective assessment. With the model promoted in dynomic form, the experimental result proves the accuracy and efficiency.
