互信息量用于采样成像系统的评价
Assessment of sampled imaging system based on mutual information
【摘要】 把信息论应用于采样成像系统中 ,用互信息量评价图像捕捉部分的性能 ,做出基于信息论的系统评价仿真曲线 ,将互信息量作为优化系统设计的一种新指标
【Abstract】 By extending information theory to sampled imaging system, the performance of image gathering device according to mutual information is assessed. An information theory based computer simulation result is given. One of the methods, which are used to optimize system design, is proposed.
