代码说明:

  matlab编写的对二值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100个字节。提取时可验证是否被修改过,如未修改,可提取隐藏信息。当有修改发生时,可以定位修改的位置,并在图上标出。标识面积占修改面积的75%,一般修改都能标出(matlab prepared binary image of the digital watermark added 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. Can be added to the information length of 100 bytes. Verifiable extraction has been modified, if modified, can extract hidden information. When a modification occurs, you can modify the location of positioning and marked maps. Logo area accounted for 75 to amend the area generally can be identified modifications)

    说明:  傅立叶变换在图像处理中的重要作用: (A) 图像增强与图像去噪 绝大部分噪音都是图像的高频分量,通过低通滤波器来滤除高频噪声;边缘也是图像的高频分量,可以通过添加高频分量来增强原始图像的边缘; (B) 图像分割与边缘检测 提取图像高频分量 (C) 图像特征提取 形状特征:傅里叶描述子 纹理特征:直接通过傅里叶系数来计算纹理特征 其他特征:将提取的特征值进行傅里叶变换来使特征具有平移、伸缩、旋转不变性 (D ) 图像压缩 可以直接通过傅里叶系数来压缩数据;常用的离散余弦变换是傅立叶变换的实变换; (Fourier transform in the important role of image processing: (A) image enhancement and image denoising Most of all images of high frequency noise by low pass filter to filter out high frequency noise edge is the image of the high frequency components can be enhanced by adding high frequency components to the edge of the original image (B) Image segmentation and edge detection High frequency components extracted image (C) image feature extraction Shape features: Fourier descriptors Texture: directly through the Fourier coefficients to calculate the texture features Other features: The characteristic value extracted by Fourier transform to the characteristics of translation, scaling, rotation invariance (D) image compression Fourier coefficients can be directly compressed data commonly used discrete cosine transform is the Fourier transform of the real transformation 朗读显示对应的拉丁字符的拼音)

    能够提取出图像I的HOG特征,返回其幅值,角度和在各个角度上的幅值。 是进行其他针对图像的HOG特征提取的前一步。(I can extract images of HOG features, return to their amplitude, angle and perspective in all of the amplitude. Is the other for image feature extraction HOG step forward.)
