摘要
从SAR图像的统计特性出发,构造了对比度塔(CP),对SAR图像进行相干斑抑制和对比度调整,并将第二代Bandelet变换用于SAR图像压缩.在bpp值较高的情况下,该方法提高了SAR图像的压缩性能,适用于方向信息比较丰富、背景复杂的SAR图像的压缩处理.
Based on the statistic characters of SAR images, and constructing contrast pyramid, take speckle,noise reduction and contrast modulation as pretreatments and use second Bandelet transform to compress SAR images in this paper. Better compression performance can be achieved when bpp value is not very low. This method is applicable for SAR images with rich directional information and complicated background.
