【摘要】 本文提出一种实现乘型图象模拟同态处理的方案和实验研究系统。利用该系统可使图象中原先隐含而难以显示之信息有较好的表现。该实验系统曾用来处理眼底图象,其效果是视网膜血管上、下交叉较易辨别,图象中可见的信息增多,有利于临床鉴别诊断。更多还原

【Abstract】 In the present paper, a briet description of homomorphic image processing principles is given and some design considerations on multiplicative homomorphic image processing by television technigue are discussed. Finally, some engineering comments are given and the experimental results are illustrated. Although the experiments done were rather preliminary, the photographic results shown seem to be comparable with that obtained by digital methods.更多还原
