BMP图象的DWT变换水印 提取,有DCT变换改写的 ,有参考价值

BMP图像基于小波分解添加及提取数字水印-BMP image extraction based on wavelet decomposition and watermark added

实现 BMP图像显示、反色、DFT以及DWT，可以通过鼠标控制来截取矩形大小的图像并显示。-Achieve BMP image display, anti-color, DFT and DWT, can be clipped image size of the rectangle by mouse control and display.
