2373 将计量逻辑学中的相关理论推广到以预粗糙代数为赋值格的粗糙逻辑上,为基于粗糙概率真度的程度化推理提供了一种可能的框架。 The theory of quantitative logic is expanded to rough logic, which makes it possible in graded reasoning in rough logic.
2374 图像色彩空间的 RGB 通道具有密切的关系,图像质量的改变会改变这样的关系。 In the image color space, the RGB channels have strong correlations. The quality change of an image willlead to the change of channel correlations.
2375 然而传统图像质量评价方法大多基于灰度图像统计特性,忽略了颜色通道间关系信息。 However, most traditional image quality assessment (IQA)methods, based on grayscale image statistics, ignore such correlation information among color channels.
2376 为充分利用颜色信息,本文基于新近提出的互补色小波变换提出一种图像质量盲评价方法。 In this paper, to utilize the color infor-mation, we propose a blind IQA method based on the recent proposed complementary color wavelet transform (CCWT).
2377 文章建立了图像互补色域自然场景统计、多尺度和方向性能量分布等模型。 We provide models for the complementary color nature scene statistics, multi-resolution and multi-directionality energy distribu-tions of an image.
2378 分析表明:这些模型不仅涵盖了传统灰度方法所能描述的信息,而且还能借助于互补色来有效表示彩色图像各通道之间的信息联系,提供表征图像质量的一组高效特征。 The analysis shows that our models not only cover the information of traditional methods, but also provide the relation information among color channels. A group of high-efficiency image quality features is then given.
2379 基于这些特征,我们提出的图像质量盲评价的方法能有效提取图像的失真统计特征,能给出与人眼主观评价图像质量结果保持高度一致、优于现有文献报道盲方法、且可与非盲(全参考)方法相比拟的评价结果。 Based on these features, our blind IQA method can effectively extract the distortion statistic features and provide assessment results. Our IQA results are agreeing with the human subjective, better than the state-of-the-art blind IQA results, and close to the full-reference ones.
2380 在极化合成孔径雷达(PolSAR)图像杂波服从 K 分布下,已有的基于多视极化白化滤波器(MPWF)的恒虚警(CFAR)检测方法不适用于等效视数为非整数情形。 In the case that the clutter of the polarimetric synthetic aperture radar (PolSAR)imagery follows K distri-bution, the existing constant false alarm rate (CFAR)detection algorithms based on multi-look polarization whitening filter(MPWF)cannot be applied to the condition that the equivalent number of looks is a non-integer.
2381 针对此问题,提出了一种具有解析虚警概率表达式的CFAR 检测方法。 To solve the problem, a CFAR detection algorithm with analytical false alarm probability expression is proposed.
2382 在乘积模型下引入 Gamma 分布纹理变量后,对 MPWF 检测量的概率密度函数(PDF)积分得到其累积分布函数(CDF),进而得到虚警概率关于检测门限的解析形式。 After introducing the Gamma distri-bution texture under the product model, the probability distribution function (PDF)of the MPWF metric is integrated to ob-tain its cumulative distribution function (CDF), and then the analytical form of the false alarm probability with respect to the detection threshold is obtained.
