Deviation 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...

Wavelet Coefficients Reduction Method Based on Standard Deviation Concept for High Quality Compressed Image

This paper proposes a method to estimate the wavelet coefficient threshold value at wavelet details subbands to archive high quality image compression. It uses the features of Discrete Wavelet Transform (DWT) where the images are decomposed into one approximate subband and three detail subbands. The detail subbands consists of Diagonal, Vertical and Horizontal subband. By using the standard dev...

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...

Local Standard Deviation Based Image Quality Metrics for JPEG Compressed Images

In this paper, we address the Full-Reference (FR) Image Quality Metric (IQM) to assess the quality of JPEG-coded images and we present a new effective and efficient IQA model, called Local Standard Deviation Based Image Quality (LSDBIQ). The approach is based on the comparison of the local standard deviation of two images. The proposed metrics is tested on four well-known databases available in...

Image quality enhancement in digital panoramic radiograph

One of the most common positioning errors in panoramic radiography is palatoglossal air space above the apices of the root of maxillary teeth. It causes a radiolucency obscuring the apices of maxillary teeth. In the case of this positioning error, the imaging should be repeated. This causes the patient be exposed to radiation again. To avoid the repetition of exposing harmful X-rays to the pati...
