| 摘 要： | 用数理统计观点，把图象看成是由纯噪声象和纯目标象叠加而成，用二元统计编码方法，对信噪比接近１的相干图象，进行了计算机模拟，获得了被噪声淹没的二元目标象，给出了对比度与目标恢复程度之间的对应关系。

| Abstract: | In the view of mathematical statistics,an image is formed by pure noise image and pure object image superimposing.The coherent image whose SNR is about 1 has been simulated by computer with binary statistic coding method.A binary object image immersed by noise has been obtained and the corresponding relation between the contrast and the recovering degree of the object is given.In theory,the binary image recognition technique of the binary statistic coding is very ef fective for processing of the practically obtained low SNR coherent and incoherent images. |
