An automated method for finding the optimal parameters of adaptive filters for speckle denoising of SAR images

open access: yesКомпьютерная оптика, 2022
Many different filters can be used to reduce multiplicative speckle noise on radar images. Most of these filters have some parameters whose values influence the result of filtering. Finding optimal values of such parameters may be a non-trivial task.

SSIM-optimal linear image restoration [PDF]

open access: yes2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008
In this paper, we present an algorithm for designing a linear equalizer that is optimal with respect to the structural similarity (SSIM) index. The optimization problem is shown to be non-convex, thereby making it non-trivial. The non-convex problem is first converted to a quasi-convex problem and then solved using a combination of first order ...

3D-SSIM for video quality assessment [PDF]

open access: yes2012 19th IEEE International Conference on Image Processing, 2012
Effective and efficient objective video quality assessment (VQA) methods are highly desirable in modern visual communication systems for performance evaluation, quality control and resource allocation purposes. Simple VQA algorithms may be developed by direct extensions of still image quality assessment (IQA) approaches on a frame-by-frame basis ...

CW-SSIM based image classification [PDF]

open access: yes2011 18th IEEE International Conference on Image Processing, 2011
Complex wavelet structural similarity (CW-SSIM) index has been proposed as a promising image similarity measure that is robust to small geometric distortions such as translation, scaling and rotation of images, but how to make the best use of it in image classification problems has not been deeply investigated.
