The use of a diffuser in synthesizing binary texture-variance masks for applications in image processing is investigated. The binary texture-variance masks are used to separate various objects in an image on the basis of their spatial texture variance. The diffuser is required to reduce the speckling present in the mask. The reduction in speckling is described quantitatively as a reduction of the misclassification probability associated with the separation of the objects into several texture classes. General results are furnished for the statistics of the field scattered by the diffuser, and these are used to obtain expressions for the misclassification probabilities in the presence of a diffuser. Some applications are furnished.
研究了在合成用于图像处理的二元纹理方差掩模中使用扩散器的情况。二元纹理方差掩模用于根据图像中各种物体的空间纹理方差来分离它们。需要扩散器来减少掩模中存在的散斑。散斑的减少被定量描述为与将物体分离成几个纹理类别相关的错误分类概率的降低。给出了关于扩散器散射场统计的一般结果，并用于获得存在扩散器时错误分类概率的表达式。还提供了一些应用。
