An image quality evaluation method based on gray prediction error 一种基于灰度预测误差统计的影像质量评价方法
In chap 5 the dissertation discusses the new method of image quality evaluation based on wavelet transform 第五章详细论述了基于小波变换的图象质量评价方法。
The main goal of this dissertation is to present a new method of image quality evaluation based on wavelet transform 文章的主体给出了一种新的基于小波变换的图象质量评价方法。
After the description of the development history and classification of the methods of image quality evaluation some typical methods is analyzed , their characteristics , good qualities and shortcomings are compared and summarized 作者还通过分析多种有代表性的图像评价方法,对现有方法的特点和优劣进行了总结和比较。
Otf , one of the most objective and effective methods that are proposed to evaluate the imaging quality of the optical system , is extensively used in the process control of the optical system design and the imaging quality evaluation and detection of the optical imaging system 光学传递函数是目前评价光学系统成像质量最客观、最有效的方法之一,广泛地应用于光学系统设计的过程控制和光学成像系统的像质评价与检测中。
The dissertation introduces the concept of " image quality " . from the point of view of people eyes " visual characteristics , a new method to evaluate image quality based on the wavelet theory is puts forward and then its efficiency is proven , at first the author describes the concept of " image quality " detailedly , po i nts out the great sense of " image quality evaluation " 文章介绍了“图像质量”的概念,并以人眼的视觉特性为出发点,基于小波理论提出了新的图象质量评价方法,并证明了该方法的有效性。首先,文章明确了“图像质量”的概念,指出了“图像质量评价”的重要意义,并给出了图像质量评价方法发展的历史和分类。
According to this , we propose a new way to renew the traditional method of subjective image quality evaluation , different to only use mse ( mean square error ) and psnr ( peak signal - to - noise ratio ) to evaluate merely on radiation distortion , and complemented quantitative description on compressed image distortion o it is significant to choose the format of video transferation and measuring precision calculation of tracking and measuring systems based on images 中国科学院长春光机与物理研究所博士学位论文据此提出了不同于传统的仅用均方误差( mse )和峰值信噪比( psnr )来评价图像灰度辐射畸变的新思路,补充了对压缩图像几何畸变的定量描述。这对于基于图像的测量跟踪系统中数字图像传输方式的选择,以及评价压缩解压算法对测量精度的影响有重要意义。
After summarized traditional evaluation methods and research on the image fusion trends , it is obvious to adopt hvs method to achieve good results . an image quality evaluation method is proposed , which is entertainment - oriented , appended with experiment results . this paper studies the image - fusion in self - control virtual photographing through three periods working , which are theory analysis , practical implantation and theory breakthrough with simulation 在分析传统的图像质量评价方法及其缺陷的基础上,指出将hvs特性引入图像计测方法中的必要性;同时,对融合图像质量评价现状进行了深入的研究,鉴于本课题研究的特殊性,建立了一套适合娱乐照相领域融合图像的质量评价方法,并给出实验分析。
