客观质量评价
相关语句
  objective quality assessment
     The degree of visual interest to the ROI of the image is regarded approximately to be an inverse measure of the acreage of the ROI. As the acreage of the ROI is zero, the method will become the objective quality assessment of image, that is to say, the objective quality assessment of image is a specific case of the method in this paper.

Research on right quality assessment of image is very meaningful in the image information project, but the objective quality assessment of image cannot always be in accordance with human vision. Any reasonable quality assessment method of image should abide fully by human subjective vision. Due to many factors such as visual psychology, culture background, surrounding environment, different applications and so on, an image can be divided into different regions of interest (ROI) by vision interests.

Research on right quality assessment of image is very meaningful in the image information project, but the objective quality assessment of image cannot always be in accordance with human vision. Any reasonable quality assessment method of image should abide fully by human subjective vision. Due to many factors such as visual psychology, culture background, surrounding environment, different applications and so on, an image can be divided into different regions of interest (ROI) by vision interests. To best advantage of human visual interests, a simplified method for subjective assessment of image is presented to an image with only one ROI in this paper. The degree of visual interest to the ROI of the image is regarded approximately to be an inverse measure of the acreage of the ROI. As the acreage of the ROI is zero, the method will become the objective quality assessment of image, that is to say, the objective quality assessment of image is a specific case of the method in this paper. The experimental results have shown the effectiveness of the proposal scheme. It is in better accordance with human subjective vision.

图象质量的正确评价是图象信息工程领域内一项很有意义的研究课题 ,但现有的图象客观评价方法并不完全符合人眼视觉特性 .合理地评价图象质量应充分遵循人眼的视觉特性 ,但由于受到人的心理、文化背景、周围环境、不同的应用场合等多种因素的影响 ,人眼对同一幅图象中的不同区域往往具有不同的感兴趣程度 ,即人眼具有视觉兴趣性特性 .该文在充分利用视觉兴趣性特性的基础上 ,针对只存在一个感兴趣区的图象 ,提出了一种简化的图象质量评价方法 .该方法近似地认为人眼对感兴趣区的兴趣程度与其面积成反比 ,当图象中感兴趣区的面积为零时 ,该文方法将退化为客观质量评价方法 ,也就是说客观质量评价方法是该方法的特例 .实验结果证明 ,该方法能够较好地符合人眼的主观视觉特性 .

The objective image quality evaluation of DCT(discrete cosine transform) compressed images is usually achieved using MSE(mean square error) and PSNR(peak signal to noise ratio) with the geometric degradation of images out of consideration, which is the very key to the optical measurement system based on position information. DCT compression experiemnts made with two images with high spatial redundancy show that MSE and PSNR do not change much under 4×4 processing block and 1∶2 compression ratio, but there is a geometric degradation of 1 or 2 pixels; considering the total error of the optical measurement system is generally only 1 or 2 pixels, a change in position of more than 1 pixel resulting from DCT compression will have a significant influence on the accuracy of the measurement system. A good deal of attention should, therefore, be paid to geometric degradation during DCT compression.

离散余弦变换 (DCT)压缩图像的客观质量评价通常采用均方误差 (MSE)和峰值信噪比 (PSNR) ,而缺乏对图像几何衰变的考虑 ,这正是基于位置信息的图像测量系统的关键。针对这一问题 ,对两幅高空间冗余图像进行DCT压缩实验研究 ,结果表明 :用 4× 4分块 ,1:2压缩比时 ,MSE和PSNR变化不大 ,但有 1或 2个像元的几何衰变。与一般情况下光学测量系统总体误差只有 1~ 2个像元比较 ,在因压缩而产生像元级的位置变化时 ,将会严重影响测量精度 ,因此对这类图像进行DCT压缩时应十分关注几何衰变
