Description: matlab编写的对灰度图像的数字水印添加与提取程序。压缩包中有示例图片。可以添加水印，结果肉眼不易分辨出变化，不影响使用。可加入信息长度达10k字节。提取时可验证是否被修改过，如未修改，可提取隐藏信息。可标记修改位置。当图像发生旋转，缩放，少量平移时，仍能提取出强水印信息，以确保图像来源。弱水印识别率高，强水印识别率不是很高，当图像变化较小时，可以工作，变化较大时，强水印也无法提取。-matlab prepared on the gray image to add the digital watermark and extraction procedures. Compression package has sample images. Can add watermarks, the results of the changes are not easily distinguishable from the naked eye, does not affect use. Information can be added up to 10k bytes in length. Verifiable extraction has been modified, if modified, can extract hidden information. Can modify the location of tags. Occurred when the image rotation, zooming, a small amount of translation were able to extract strong watermark information, to ensure that the image source. Weak watermark high recognition rate, strong watermark is not very high recognition rate, when the image changes in small, can work, changes in large, strong watermark can not be extracted.

Description: 该gui函数基本上包括图像处理里面的最基本处理，相当于一个小型photoshop。比如读取文件，几何变换中的垂直镜像，平移，旋转，缩放；正交变换的DFT，FFT，DCT，DST，DHT，DWashT；灰度处理中的反色，直方图均衡，全局线性变换，分段线性变换，指数非线性变换，对数非线性变换；图像增强里面的加噪声，平滑，锐化，伪彩色增强；图像分割里面的灰度阈值法，Robert，Laplace，sobel，prewitt，canny算子边缘检测法；图像恢复里面的直接逆滤波，维纳滤波；图像编码里面的霍夫曼编码，行程编码-Basically, the gui functions including the most basic image processing inside the handle, which is equivalent to a small photoshop. For example, read the document, the geometric transformation of the vertical mirroring, shifting, rotating, zooming orthogonal transformation of the DFT, FFT, DCT, DST, DHT, DWashT anti-gray color processing, histogram equalization, global linear transformation , piecewise linear transformation, index of non-linear transform of the number of non-linear transformation image enhancement which increases the noise, smoothing, sharpening, pseudo-color enhancement the gray-scale image segmentation inside the threshold, Robert, Laplace, sobel, prewitt, canny edge detection operator method image restoration inside direct inverse filtering, Wiener filtering image coding inside the Huffman code, and so on Run-Length Coding Platform: |

Description: my project is "implementation of mini-PACS in health care system".
the image is in std DICOM format & is compressed using wavelet based JPEG2000 & transferred using JPIP to the reciever where the reciever will have an editor(that we are going to develop in visual studio C++) to view the medical image & has many options that can be performed i.e. rotation of the image, zooming , region of interest, skewing & saving in desired form.

Description: matlab实现用双线性插值法放大和缩小图像-Zooming and Shrinking Images by Bilinear Interpolation
(a) Write a computer program capable of zooming and shrinking an image by bilinear interpolation. The input to your program is the desired size of the resulting image in the horizontal and vertical direction. You may ignore aliasing effects.
(b) Download Fig. 2.19(a) and use your program to shrink this image 1024 x 1024 to 256 x 256 pixels.
(c) Use your program to zoom the image in (b) back to 1024 x 1024. Explain the reasons for their differences.
