“…On the contrary, we determine the informative patches within the blurry image using mathematical equations for characteristics, edge strength [17] and uniformity of edge direction. Motivated by the structure of the edge strength used in [17] for image quality assessment, we propose a directional edge strength map and uniformity map described as follows. Denote the observed blurry image as 1 [ , , , , ] ,…”

This paper proposes a fast patch-based de-blurring algorithm including kernel estimation based on the angle between the edge and the blur direction. For de-blurring, image patches from the most informative edges in the blurry image are used to estimate a kernel with low computational cost. Moreover, the kernels of each patch are estimated based on the correlation between the edge direction and the blur direction. This makes the final kernel more reliable and creates an accurate latent image from the blurry image. The combination of directionally oriented kernel estimation and patch-based de-blurring is faster and more accurate than existing state-of-the art methods. Experimental results using various test images show that the proposed method achieves its objectives: speed and accuracy. key words: de-blurring, edge direction, image restoration, kernel estimation, motion blur.

“…To overcome the limitations of pixel difference based quality metrics, structural assessment based quality metrics were introduced such as structural similarity index (SSIM) [2], structural content (SC), complex wavelet structural similarity index (CWSSIM) [3], feature similarity index (FSIM) [4] and edge strength similarity index (ESSIM) [5], etc. Out of which structural similarity index became much popular because of its accuracy to determine quality of the image.…”

“…In reference paper [4], authors believe that human vision system interpret image according to low level images and they have used phase congruency as main feature in their work. ESSIM in [5] considers anisotropic regularity and irregularity of edge into proposed metric. This quality metric could be classified as edge based quality metric too.…”

“…Also, authors in [8] proved that universal image quality index (UIQI) is superior metric than MSE with simple mathematical model. Literatures [1][2][3][4][5][6][7][8] represent variety of quality metrics but the common consideration for their design is Gaussian noise or Gaussian distortion. As per our knowledge, we come across only one paper in which quality metric is specifically designed for speckle noise.…”

“…The SGF is used particularly to get edge information at different orientations and also to get more degree of freedom in selecting the edges in the image. The application of steerable filter in IQA is motivated by the characteristics of edges as given in [18] which are (i) Local regularity/ smoothness / continuity and local irregularity /oscillation/ discontinuity which are also orthogonal to each other. (ii) There also exists anisotropic structures in the image and the edges always stretch out in multiple directions.…”

Abstract-In literature, oriented filters are used for low-level vision tasks. In this paper, we propose use of steerable Gaussian filter in image quality assessment. Human visual system is more sensitive to multidirectional edges present in natural images. The most degradation in image quality is caused due to its edges. In this work, an edge based metric termed as steerable Gaussian filtering (SGF) quality index is proposed as objective measure for image quality assessment. The performance of the proposed technique is evaluated over multiple databases. The experimental result shows that proposed method is more reliable and outperform the conventional image quality assessment method.
