By Sebastiano Battiato

This booklet constitutes the completely refereed court cases of the sixteenth foreign convention on complicated suggestions for clever imaginative and prescient structures, ACIVS 2015, held Catania, Italy, in October 2015. The seventy six revised complete papers have been rigorously chosen from 129 submissions.

Acivs 2015 is a convention concentrating on suggestions for development adaptive, clever, secure and safe imaging platforms. the focal point of the convention is on following subject: low-level snapshot processing, video processing and digicam networks, movement and monitoring, protection, forensics and biometrics, intensity and 3D, photo caliber development and overview, class and popularity, multidimensional sign processing, multimedia compression, retrieval, and navigation.

Edges play the most important role in the ringing suppression problem because ringing effect is the most noticeable near strong edges. We have also discovered that some blocks with edges are not represented well enough in the testing phase due to absence of edges with approximately the same direction in the training set. In order to improve the performance for these blocks we extend the dictionaries by their rotated versions after the learning process. Denote the Rota as the operator that rotates all atoms in the dictionary by a◦ , then the extended dictionaries are built as follows (here Dsbase , Drbase are the dictionaries obtained in the dictionary learning phase): Ds = Dsbase ; Rot90 (Dsbase ); Rot180 (Dsbase ); Rot270 (Dsbase ) Dr = Drbase ; Rot90 (Drbase ); Rot180 (Drbase ); Rot270 (Drbase ) We use only these three rotations (90◦ , 180◦ , 270◦ ) because they can be applied to the square images without introducing interpolation errors.
