首先介绍图像融合和联合稀疏表示的研究背景和研究现状,并给出基于联合稀疏表示的图像融合方法的基本框架,然后就联合稀疏表示图像融合方法的基本原理进行了简单介绍,最后本文给出基于联合稀疏表示的图像融合实验效果图,并作出了实验分析。
通过实验后的融合视觉效果图,我们可以得出结论:基于联合稀疏表示的图像融合方法能够很好地实现图像的融合,并具有很好的视觉效果。
关键词:联合稀疏表示,滑窗技术,图像融合,稀疏系数Image Fusion Based on Joint Sparse RepresentationA bstract: In this paper, the potential application of joint sparse representation in the image fusion is studied bothin theoretical analysis and experimental simulation. First, we provide a brief introduction to the background and present situation of joint sparse representation. Then we introduce the skeleton structure of joint sparse representation for fusing images. After that, we introduce the basic theory of joint sparse representation, in which we obtains sparse coefficients by joint sparse representation optimization problem and we get the fused coefficient by the fused rules based on impact factor. Finally, The experimental results indicate that the three algorithms provides efficiency and promising fusion results, which demonstrates the great and benefits of combining the joint sparse representation and image fusion.Index Terms: joint sparse representation, image fusion, sparse coefficient1. 引言随着科学技术的发展,由于单一传感器获取信息有限,难以满足实际需求,传感器的工作模式由单工作模式转变为多工作模式[1]。

单通道16位采样率为44.1K音频信号进行压缩,实现.mp3格式的数据结构(上海大学DSP技术及其应用 )

上海大学2014~2015学年秋季学期研究生课程考试文献阅读报告课程名称:DSP技术及其应用课程编号:071000907题目: 单通道16位、采样频率44.1K音频信号压缩,实现*.MP3格式的数据结构研究生姓名: 学号:评语:成绩: 任课教师:评阅日期:单通道16位、采样率为44.1K音频信号进行压缩,实现*.mp3格式的数据结构2015/1/15摘要:在目前的信息社会,需要应用和传输大量的语音信息,这些信息中存在着大量的冗余,如果不去除掉这些冗余,在其传输和存储的过程中,将会占用大量的资源,因此,语音压缩技术受到了人们的普遍关注。
在此基础上,对MP3编码器的基本原理和基本结构进行了研究,并对其几个关键模块包括心里声学模型、子带滤波、量化编码等进行了深入的研究。
研究结果表明MP3要具有良好的编码质量,本文着重于如何将音频信号压缩为MP3格式。
关键词:MP3编解码;音频;算法原理;算法16-channel sampling rate of 44.1K audio signal compression,implement data structures mp3 formatAbstract:In the current information society,there is much voice information which contains mass of redundancy.It will take up vast resources in transmission and storage processes if the redundant is not removed.Therefore,voice compression technology has been paid widely attention.Based on all of these,the basic principle and structure of MPEG-1 layer3 audio code is investigated.Especially,several key modules such as psychoacoustic model,sub-band filtering and quantization coding are carried on further study.The research results show that the MP3 encoding quality to have,This article focuses on how to get the audio signal compression to MP3 format。
