This ebook constitutes the completely refereed court cases of the sixteenth overseas convention on complex strategies for clever imaginative and prescient platforms, ACIVS 2015, held Catania, Italy, in October 2015. The seventy six revised complete papers have been conscientiously chosen from 129 submissions.

Acivs 2015 is a convention targeting suggestions for construction adaptive, clever, secure and safe imaging structures. the point of interest of the convention is on following subject: low-level photo processing, video processing and digital camera networks, movement and monitoring, protection, forensics and biometrics, intensity and 3D, photograph caliber development and review, type and popularity, multidimensional sign processing, multimedia compression, retrieval, and navigation.

Xn is defined X So the X α-sparse. ,n xi 0 . V. Umnov et al. t. X 0,inf ≤ α. This problem can be solved using any sparse dictionary learning algorithm. In our work we use the K-SVD algorithm [1] for dictionary learning and OMP algorithm [10] for sparse coding. 3 Ringing Suppression Method The proposed method requires a set of images for learning. We split all images into overlapping 6 × 6 blocks and process each block separately. The images from the learning set are used to create a set of corresponding original blocks and blocks with ringing effect.

Authors of [12] propose a new descriptor called RSD-HoG. It is based on the RSD-DOG 25 orientation of the edges. The edge orientations are extracted by using a rotating half Gaussian kernel. The descriptor is constructed in a novel way, by embedding the response of the rotating half Gaussian kernel in a Histogram of oriented Gradient (HoG) framework. e. how much the curve bends at that point. The authors of [16] use an oriented second derivative filter of Gaussians to capture isotropic as well as anisotropic characteristics of surface by the use of single scale for descriptor generation.

The visual results show that the estimated blur is fitted with human blur perception. The quantitative evaluation is made comparing bl index with OCR accuracy. We calculated SROCC for 25 sets of the database DIQA with the estimated blur. This experiment shows that our blur estimation method can rank and select images with best OCR accuracy. In addition, the measured Pearson’s correlation scores for 25 sets show that our method outperforms unsupervised and supervised approaches. Next step is to use the present computation in order to improve the quality of the document and in particular the OCR accuracy.
