Description: 数字图像处理骨架提取，能将一个二值图像的骨架提取出来进行后续处理。骨架是一种非常重要的图像几何特征，在图像几何形态分析及相关领域具有非常广泛的应用，利用骨架表示原始图像，可以在保持图像重要拓扑特征的前提下，减少图像中的冗余信息。骨架既能压缩图像数据，保留区域的连通性和拓扑性，描述区域轮廓的几何特征，又能使原始图像完全或部分地从骨架中恢复或重构。-Skeleton extraction of digital image processing, to a binary image of the skeleton extracted follow-up to deal with. Skeleton is a very important feature of the image geometry, geometry in image analysis and related fields with a very wide range of applications, the use of the original image frame that may be important in maintaining the topological characteristics of the image under the premise of reducing the redundant information in images. Skeleton can compress image data, the reserved area of connectivity and topology, and describes the outline of the geometric characteristics of the region, and it also enabled the original image in whole or in part to recover from the skeleton or remodeling.

Description: The discrete cosine transform (DCT) is a technique for converting a signal into elementary
frequency components. It is widely used in image compression. Here we develop some simple
functions to compute the DCT and to compress images.
These functions illustrate the power of Mathematica in the prototyping of image processing
algorithms.
