Human motion analysis has proven to be a great source of information for a wide range of applications. Several approaches for a detailed and accurate motion analysis have been proposed in the literature, as well as an almost proportional number of dedicated datasets. The relatively recent arrival of depth sensors contributed to an increasing intere...

Several approaches based on human gait have been proposed in the literature, either for medical research reasons, smart surveillance, human-machine interaction, or other purposes, whose validation highly depends on the access to common input data through available datasets, enabling a coherent performance comparison. The advent of depth sensors lev...

In order to study the mechanisms behind the human motion and its disorders, and to comprehend how do neuromuscular impairments affect the human movements, it is crucial to know the human musculoskeletal system. This knowledge is also essential to effectively model and analyse the musculoskeletal system, and to classify the human movement. With this...

Content Based Image Retrieval (CBIR) is a challenging and active topic of research. This paper focuses on the shape of the represented objects as the main criterion in respect to evaluate the relevance of the retrieval results. There are several shape descriptors described in the literature, which are reported to achieve good results. However some...

Content based retrieval and recognition of objects represented in images is a challenging problem making it an active research topic. Shape analysis is one of the main approaches to the problem. In this paper we propose the use of a reduced set of features to describe 2D shapes in images. The design of the proposed technique aims to result in a sho...

Nowadays, with the large amount of image databases available, there is the need to access them in the most various and easiest ways. For many applications, an expeditious manner to fulfill such need encompasses partitioning images by their content both for indexing or retrieval purposes. In this paper we propose a method to group binary images in r...

Realistic facial synthesis is one of the most fundamental problems in computer graphics and one of the most difficult. Human lips synchronization of the faces is very important part of this. In this paper it solves the issue of how to make human lips synchronization in one of the most popular 3D modelling software - Autodesk Maya. It is described a...
