资源说明:This letter introduces a novel estimator of equivalent number of looks (ENL) that can be applied to any distribution of texture model, i. e., an estimator that is texture invariant. The novel estimator is the Development of Trace Moments (DTM), which cancels the textural variation using trace moments. Five forms of the DTM estimator using submatrices are presented and compared with each other. The results show that the full-dimensional matrix form seems to be the best in performance and computat
