Description: research on against geometry attacks watermarking technology. A digital Watermarking scheme, which is based on combination of simple and reliable harries detector and image normalization, is proposed. The feather points remain holding after geometry attack. Applying image normalization to these non-overlapped circles which centered at the feature points, after that, we can determine area for watermark embedding. -research on against geometry attacks watermarking technology.

Description: 图像的二值化处理就是讲图像上的点的灰度置为0或255，也就是讲整个图像呈现出明显的黑白效果。即将256个亮度等级的灰度图像通过适当的阀值选取而获得仍然可以反映图像整体和局部特征的二值化图像。-Binary image processing is to say the point of image gray-scale home for 0 or 255, that is, speaking of the images clearly show the effect of black and white. Brightness is about 256 levels of gray-scale image through appropriate threshold can be selected to reflect the characteristics of the overall and partial image of the binary image. Platform: |
