Description: 在视频编解码中,存在着两种不同的图像质量评价方式。一种方式是采用观察者的主观 感觉进行判断;另一种方式是采用客观的图像质量评价方式。这两种评价方式各有优点,但 也有不同的缺陷。主观质量评价的优点在于考虑了具体的需求,能够与观察者交互,但是其 缺点是太具有随意性, 很难给出定量的评价; 客观质量评价的优点在于能够给出定量的评价, 但存在的问题是目前还不能找到一种能够普遍适用的客观质量评价方法-In video coding, there are two different image quality evaluation. One way is to use observers to judge the subjective feeling Another way is to use an objective image quality evaluation. The two evaluation methods have advantages, but also have different defects. The advantage of the subjective quality evaluation needs to consider specific, can interact with the observer, but the drawback is that too with the arbitrary, difficult to give a quantitative evaluation objective quality evaluation of the advantage of able to give a quantitative evaluation, but there The problem is that currently can not find a way to generally applicable objective quality evaluation method

Description: 图像质量评价方法研究进展 :图像质量评价是图像处理领域的研究热点。该文综合论述了图像质量的主观和客观评价方法,重点阐述了 单视点图像质量的客观评价方法。对目前比较常用的峰值信噪比和均方误差全参考评价算法进行了分析并指出其存 在的问题。然后,对基于误差敏感度和基于结构相似度的评价算法进行了论述和分析,并对质降和无参考评价方法 进行了综述。根据视点的个数,图像质量评价可分为对传统单视点图像和立体图像的评价。该文还对立体图像质量 评价算法进行了分析讨论。最后,就图像质量评价算法的进一步发展提出了若干技术与研究方向的展望。-Image Quality Assessment (IQA) is a hot research area in the field of image processing. In this paper, objective and subjective IQA methods are reviewed, and more attention is paid to the former. PSNR and MSE, which are commonly used to assess the quality, are analyzed in detail and their defects are given. The models based on error sensitivity and structure distortion of images are two critical methods in IQA, and the survey presents their key techniques and challenge problems. The reduced reference and no reference methods are also presented in this survey. Based on the number of view, IQA are classified into two major categories, namely, monoscopic image IQA and stereoscopic image IQA. This survey also makes an introduction of the stereoscopic image IQA. Finally, the survey lists several perspective sub-fields and topics in IQA progress.

Description: Image Fusion is the process of combining information of two or more images into a single image which can retain all important features of the all original images. Input to fusion is a set of images taken from different modalities of the same scene. Output is an image of better quality which quality depends on a particular application. The objective of fusion is to generate a resultant image which describes a scene better or even higher than any single image with respect to some relevant properties providing a highly informative image. These fusion techniques are especially beneficial in diagnosing and treating cancer in field of medicine. This paper focuses on the development of a different image fusion method using Dual Tree Complex Wavelet Transform. Experimental results show that the proposed algorithm has a better visual quality than the base methods. Also the result if the fused image has been evaluated using a set of quality metrics. -Image Fusion is the process of combining information of two or more images into a single image which can retain all important features of the all original images.
