The two-volume set LNCS 6978 + 6979 constitutes the proceedings of the 16th International Conference on Image Analysis and Processing, ICIAP 2011, held in Ravenna, Italy, in September 2011. The total of 121 papers presented was carefully reviewed and selected from 175 submissions. The papers are divided into 10 oral sessions, comprising 44 papers, and three post sessions, comprising 77 papers. They deal with the following topics: image analysis and representation; image segmentation; pattern analysis and classification;forensics, security and document analysis; video analysis and processing; biometry; shape analysis; low-level color image processing and its applications; medical imaging; image analysis and pattern recognition; image and video analysis and processing and its applications.

This volume collects the papers presented at the "Specialists' Meeting on Nuclear Level Densities", held in Bologna 15 - 17 November, 1989, which gathered most of the scientists working in the field. The papers cover all the major aspects of the level density problem both from the theoretical and the experimental viewpoint, including the subject of partial level densities. In particular, moment method, collective vector method, interacting boson model, static path approximation and combinatorial approach are discussed. Effects of the residual interactions and nuclear structure are also addressed, giving a state-of-art reveiw of our present knowledge on nuclear level densities.
