Normalized correlation coefficient (NCC) and mean structural similarity index measure (MSSIM) are two well-known functions that measure similarity between two images. This paper presents a comparative false-positive rate (FPR) and the false-negative rate (FNR) analysis of these two functions for ...
Determination of the Minimum Mean Structural Similarity Index (mSSIM) Necessary to Preserve Image Quality When Utilizing Compressed Sensing MR in NeuroimagingS Sherry
Specifically, we study two different implementations of the structural similarity index: the first applies it to short and fixed time-domain frames of an audio sequence while the second decomposes the audio signals into a non-redundant, time-frequency map and then compares the structural similarity ...
superior results evaluated in terms of peak signal-to-noise ratio (PSNR), structural similarity index (SSIM), Edge preservation Index (EPI), and Equivalent Number of look (ENL), in comparison to widely known methods such as windowed Fourier transform method, Lee filter, Weiner filter. Further...

It is not only taking the geometric and photometric similarities into account, but also makes use of the local structural similarity to smooth the images. By using the local structural information, the non-homogeneous regions in the images have been identified. In the homogeneous region, only low...
6.4.8Structural Similarity Index (SSIM) SSIMmeasures the difference between the target and predicted density maps over three attributes i.e., brightness, contrast, and structure. Similar to PSNR, the value of SSIM is also in the range of [0–1] and the higher value is preferred over lower...
It is known that the Mean Squared Error (MSE) is not an effective index to describe the perceptual fidelity of images. Numerous perceptual fidelity indices have been developed, while the representatives include the Structural SIMilarity (SSIM) index and its variants. However, most of those ...
upto 99% density of SPN against standard Grey scale images, color images and video databases, in terms of Peak Signal to Noise Ratio (PSNR), Image Enhancement Factor (IEF) and Structural Similarity Index (SSIM). It has been observed that the proposed algorithms exhibit excellent noise suppressio...
