lsb空域水印算法，dct水印算法，dwt水印算法，处理灰度水印以及彩色图像水印，同时还有字符水印嵌入音频中。分别有着三个GUI界面实现不同功能。欢迎批评指正！(lsb airspace watermarking algorithm, dct watermarking algorithm, dwt watermarking algorithm, the watermark process grayscale and color images watermarking, as well as the characters in the watermark embedded audio. Respectively GUI interface has three different functions. Welcome criticism correction!)

说明：  内窥镜图像的细节增强和亮度增强算法，适用于胃部图像处理(Endoscopic image detail enhancement and brightness enhancement algorithm for stomach image processing)

关于高光谱图像的图像处理技术，RX异常检测技术，代码功能强大，且代码注释很多，对学习很有帮助。(Hyperspectral image on image processing techniques, RX Anomaly Detection technology, powerful code feature, and many code comments, learning helpful.)

说明：  1.学习使用fft2,ifft2,fftshift,ifftshift函数。用fft2函数对”lena.bmp”做二维傅立叶变换，并显示其频谱，用fftshift函数将频谱坐标原点移动到图像中心。用ifft2函数做傅立叶反变换。（提示：显示频谱时，可以先对频谱取对数，这样可以压缩动态范围很大的频谱，获得更好的显示效果）(1. Learn to use fft2, ifft2, fftshift, ifftshift functions. With the FFT 2 function, the lena.bmp'The two-dimensional Fourier transform is performed and the spectrum is displayed. The origin of the spectrum coordinate is moved to the center of the image by using the FFT shift function. The inverse Fourier transform is done with ifft2 function. (Note: when displaying the spectrum, the logarithm of the spectrum can be taken first, so that the spectrum with a large dynamic range can be compressed to obtain better display effect.))
