A book review of Image and Video Compression for Multimedia Engineering ¾ Fundamentals, Algorithms, and Standards, by Yun Q. Shi and Huifang Sun Image and video compression is one of the turnkey technologies, and often indispensable, to visual communication and multimedia engineering. I am very please to see such timely and outstanding book, which is jointly written by two internationally well-known scholars, one from academia and the other from industry, and also a veteran contributor in the MPEG standards arena. With much interests and admiration while reading this book, I would like to highlight my perspectives in reviewing the book as follows. 1. The entire book (with 480 pages in total) consists of twenty chapters and is properly divided into four parts. The logical ordering of these chapters and their sections is excellent with balanced treatment throughout. The book has its unique way in partitioning the vast material in this field that I can not find it in any other books. 2. The fundamental theories and concepts have been contained in the first part (i.e., the first 6 chapters). They are written in a systematically manner ¾ step-by-step, clearly and succinctly. This part lays a solid foundation for the remaining parts of the book. Together with Part III commented in the following, these two parts serve as the foundation of finalized image and video compression standards. 3. The topic of Motion Estimation covered in Part III is a special pre-requisite to video compression. This part is well-written and contains many updated research results. It not only clearly describes the block-matching methodology that has been adopted in all video coding standards, but also covers two intimately related techniques ¾ Pel Recursive and Optical Flow, in order to form a complete treatment and appreciation for the entire 2-D motion estimation methods. In particular, I found that the last chapter of this part (i.e., Chapter 14) is very unique and interesting. It offers insigh

矢量压缩 vector_compression库包含一些用于压缩和解压缩 3D 和 4D(单位)向量的函数。 它是为团队参加。 挑战规定在与机器人的通信链路上强制执行 9600 比特/秒的带宽限制,只允许一秒的小突发高带宽通信。 因此,我们必须尽可能地压缩我们希望以更高速率(高达 10Hz)发送的命令和反馈。 虽然通用无损压缩(例如 LZMA)很有用,但您可以使用针对特定任务定制的(有损)压缩例程来实现更高的压缩率和确定性行为。 此类算法最初通常是为 CPU 和 GPU 之间的快速数据传输而开发的,但在这种低带宽情况下也同样有效。 这个小库包含例程 (解)有符号浮点数到/从任意位宽的压缩 (de) 使用将四元数压缩到/从 5 个字节 (de) 使用面心立方堆积 (FCC) 晶格将 3D 向量压缩为任意位宽。 它还包含大多数例程的单元测试。 建造和使用 该库可以构建为 ROS catk

改进kmeans算法matlab代码 通过K均值聚类对矢量进行量化: 整个代码库,图像和说明可在此存储库中找到。 加载图像: 1.1在本项目中,我们使用了NCSU工程大楼校园的图像,如下所示: 该图像已加载以下MATLAB代码(未读取): %1。加载图像(EB的视图):I = imread('ncsu.jpg'); 图(1),imshow(I); title('原始输入RGB图像'); 1.2然后,使用下面的MATLAB代码(rgb2gray)将输入的RGB图像转换为灰度图像: 从RGB转换为灰度图像:rgbI = rgb2gray(I); Figure(2),imshow(rgbI); title('灰色图像'); 1.3现在,为了简化数学,我们将图像调整为适当的尺寸,其中我们选择min {M,N}为2的幂,并且max {M,N}为2的幂的倍数。 在我们的例子中,我们取M = 512和N = 2X512。 我们正在使用以下MATLAB代码调整rgb图像的大小: %处理图像以获取正确的尺寸%获取灰色图像的尺寸:[M,N] = size(rgbI); %将图像重塑为尺寸M = 512,N
