Recently, we are working on radar image processing (joint with Dr. Pengfei Zhang). Here are some examples Radar image segmentation (parameter alpha=0.7). Example 2 (parameter alpha=0.4). Example 3, the best result so far (after certain artificial semi-auto manipulations). Applications of nonlinear analysis in image/signal studies We are also working on the expression and enhancement of signal via various (standard or non-standard) methods. Other examples involving sound. To come.
