Image-Segmentation-Method
本文主要研究基于水平集方法的活动轮廓模型图像分割，在回顾活动轮廓模型发展的基础上，介绍了曲线演化理论及其水平集方法，证明了水平集方法可以有稳定的数值实现方式且其处理拓扑变化的自然性，进一步引出了变分水平集方法。本文介绍了两种不同的几何活动轮廓模型：基于梯度信息的李纯明模型以及基于区域信息的 Chan-Vese 模型（C-V 模型）。在分析上述两模型的优缺点上，提出了一种改进的 C-V 模型，改进模型引入了距离约束项，同时对基于区域的外部能量项进行了改进，使得水平集函数重新初始化寓于模型的演化之中，分割结果对参数的依赖性减小。 (This paper mainly study image segmentation of active contour model based on level set. After reviewing the development of the active contour model, curve evolution and level set method are presented, then we proved that the level set method has a stable numerical realization and can describe the topology change of the contour naturally, in addition we introduce level set of variational method. We introduce two different GAC models in this paper: Li Chunming model which is based on gradient information and Chan-Vese model （C-V model） which is based on region information. Based on the drawbacks and advantages of these two models, we improve the C-V model by adding penalizing energy term of signed distance function, at the same time, mending the external energy term which based on region information, then the re-initialization of the level set can accomplish in the model evolution, and the degree of the segmentation result depend on the parameters decline. )

JPEGCompression
编码：（1）进行颜色转换，将RGB格式转换为YUV格式。（2）将待编码的N×N的图像分解成(N/8)^ 2 个大小为8×8的子图像。（3）对每个子图像进行DCT变换，得到各子图像的变换系数。这一步的实质是把空间域表示的图像转换成频率域表示的图像。（4）对变换系数进行量化。（5）进行Z字形重排（6）使用霍夫曼变长变码编码器对量化的系数进行编码，得到压缩后的图像（数据）。解码：（1）对压缩的图像数据进行解码，得到用量化系数表示的图像数据。（2）进行反Z字型重排（3）用与编码时相同的量化函数或量化值表对用量化系数表示的图像数据进行逆量化，得到每个子图像的变换系数。（4）对逆量化得到的每个子图像的变换系数进行反向正交变换（如反向DCT变换等），得到(N/8)^2 个大小为8×8的子图像。（5）将(N/8)^2 个大小为8×8的子图像重构成一个N×N的图像。（6）进行颜色组合，将YUV格式转换为RGB格式图像。(JPEG compression and decompression process)
