As a result, many image processing methodologies have been recently extended to take advantage of alternative visual quality measures, the most prominent of which is the Structural Similarity Index Measure (SSIM). The superiority of the latter over Euclidean-based metrics have been demonstrated in ...
Finally, Structural Similarity Index Measurement (SSIM) is used to measure the similarity of palmprints and judge the palmprint category for classification. The recognition results of proposed method are stable in the PolyU palmprint database and the Blurred-PolyU palmprint database, moreover, the ...

You can create images for direct comparison with the Imatest Test charts module (button on the right of the Imatest main window). Here is an example, for the Spilled Coins chart, which is designed to measure the effects of signal processing on texture. ...

(e.g., spatial patches extracted from each image). If we consider one of the signals to have perfect quality, then the similarity measure can serve as a quantitative measurement of the quality of the second signal. The system separates the task of similarity measurement into three comparisons:...

In this paper we propose a novel algorithm based on Independent Component Analysis (ICA) coupled with a modified Structural Similarity Index Measure (m-SSIM) for localization of OD. We have tested our method on 100 normal retinal images (achieving 100 % success) and 232 diseased retinal images...
