| 摘 要： | 提出一种基于对比度敏感度的无参考图像清晰度评价方法,用于评价光测设备无参考电视图像的清晰度.首先通过低通滤波器构造原始图像的参考图像,并对两者进行离散余弦变换(DCT),其次将变换后的中频系数和高频系数各分为高低两档后进行离散余弦反变换处理得到各自子图像,然后计算相应子图像的结构相似度SSIM,最后将各子图像结构相似度... |

| Abstract: | A no reference image sharpness assessment method based on the property of Contrast Sensitivity Function(CSF) was proposed to realize the sharpness assessment of optical measurement equipment without reference television images.Firstly,a reference image for an original was constructed by a low-pass filter and both images were performed the Discrete Cosine Transform(DCT),and intermediate frequency coefficients and high frequency coefficients are divided into two parts respectively to be performed the Inverse ... |
