代码说明:

  数字图像快速傅里叶变换(FFT)。将图像转化成二维灰度图像后再做FFT变换,并输出变换后的幅值图。(Digital image fast Fourier transform (FFT).The image is transformed into a two-dimensional gray level image and then the FFT transformation is made, and the amplitude diagram is output after the transformation.)

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    图像 自动 标注 通过分析 训练集 ,学习 图像 和标注词 之间的关系,得出 之间的关系,得出 一些规则, 然后使用这些规则 自动 推导出 图像 最适合的标注词 ,这些标注词代表了图像的 ,这些标注词代表了图像的 高层 语义信息 。(Automatic image annotation by analyzing the training set, learning image and mark the relationship between words, the relationship between the draw, draw some rules, and then use these rules to automatically derive the most suitable image annotation words, these words represent the image annotation , these words represent the image annotation level semantic information.)

    在逆向工程中通过测量仪器得到的产品外观表面的点数据集合也称之为点云,通常使用三维坐标测量机所得到的点数量比较少点与点的间距也比较大,叫稀疏点云;而使用三维激光扫描仪或照相式扫描仪得到的点云点数量比较大并且比较密集,叫密集点云。(Data collection point in the surface appearance of the product obtained by reverse engineering measurement instruments, also known as point clouds, usually spaced three-dimensional coordinate measuring machine number of points obtained in relatively small dots are relatively large, called sparse point cloud while the number of point cloud using the three-dimensional laser scanner or camera scanner get bigger and more intensive, called dense point clouds.)

    Jsteg算法实现,Jsteg是一种基于JPEG的常用信息隐藏算法步骤如下: 首先,把掩体图像分为不重叠的8*8的子块,对每一子块进行DCT并对变换得到的DCT系数进行量化 其次,将待隐藏的信息进行加密,将加密结果嵌入到量化后值不为0,1或-1的DCT系数的最 低有效位(LSB)中,其嵌入顺序是按zigzag扫描顺序进行的。最后,用JPEG的嫡编码(包括哈夫曼编码,游程编码及DPCM)对嵌入秘密信息后的每一子块进行编码,从而得到一个含有秘密信息的JPEG stego文件。(Jsteg Algorithm)
