In order to realize movement target detection and tracking, the sonar image sequence movement target detection based on Surfacelet transform at complex background is proposed. Firstly, sonar image characteristic area extract based on Surfacelet transform, secondly, extract characteristic quantities and confirm correspondence between frames of characteristic quantities, at last, calculate motion parameters...
A new method for sonar image denoising which colligated the strongpoint of Surfacelet transform and sample matrix was presented. Surfacelet transform is good at multidimensional signal processing, but Surfacelet transform is not adapted to process 2-D image directly. In this paper, a noise images based on sample matrix is cycled spinning at a direction and compressed to image sequence, which is implemented...
