Reduced-Reference Image Quality Assessment based on saliency region extraction
In this paper, a novel saliency theory based RR-IQA metric is introduced. As the human visual system is sensitive to the salient region, evaluating the image quality based on the salient region could increase the accuracy of the algorithm. In order to extract the salient regions, we use blob decomposition (BD) tool as a texture component descriptor. A new method for blob decomposition is propos...
متن کاملObjective Image Quality Assessment of Multiply Distorted Images
Subjective studies have been conducted in the past to obtain human judgments of visual quality on distorted images in order to benchmark objective image quality assessment (IQA) algorithms. However, existing subjective studies obtained human ratings on images that were corrupted by only one of many possible distortions. However, the majority of images that are available for consumption may gene...
متن کاملFull Reference Image Quality Assessment based on Local Statistics1
Assessment of image quality based on structural information is a relevant topic in the image processing field. A new method to assess image quality is presented. It is based on the comparison of first and second order moments of the local variance distribution of two images. This new quality index is better suited to assess the non-stationarity of images, therefore it explicitly focuses on the ...
متن کاملA Novel Subsampling Method for 3D Multimodality Medical Image Registration Based on Mutual Information
Mutual information (MI) is a widely used similarity metric for multimodality image registration. However, it involves an extremely high computational time especially when it is applied to volume images. Moreover, its robustness is affected by existence of local maxima. The multi-resolution pyramid approaches have been proposed to speed up the registration process and increase the accuracy of th...
متن کاملDeviation Based Pooling Strategies For Full Reference Image Quality Assessment
The state-of-the-art pooling strategies for perceptual image quality assessment (IQA) are based on the mean and the weighted mean. They are robust pooling strategies which usually provide a moderate to high performance for different IQAs. Recently, standard deviation (SD) pooling was also proposed. Although, this deviation pooling provides a very high performance for a few IQAs, its performance...
