Mid-term impact estimation on evaluations of rural development programs

Mid-term evaluations are carried out during the implementation of the program and shall indicate whether it is necessary to redirect and make corrections before the ex-post evaluation, or for the next programming period. One of the core elements within these evaluations is the estimation of programs expected impacts. This is especially important for the Commission in order to support sound decision making, but also a very challenging task, as many evaluators have pointed out, mainly due to the lack of available data at the time the study had to be carried out. The aim of this study is therefore to analyze how impact estimation has been done in all European Union regions, as well as the problems encountered by evaluators.

Development of a hand-gesture recognition system for human-computer interaction

The aim of this Master Thesis is the analysis, design and development of a robust and reliable Human-Computer Interaction interface, based on visual hand-gesture recognition. The implementation of the required functions is oriented to the simulation of a classical hardware interaction device: the mouse, by recognizing a specific hand-gesture vocabulary in color video sequences. For this purpose, a prototype of a hand-gesture recognition system has been designed and implemented, which is composed of three stages: detection, tracking and recognition. This system is based on machine learning methods and pattern recognition techniques, which have been integrated together with other image processing approaches to get a high recognition accuracy and a low computational cost. Regarding pattern recongition techniques, several algorithms and strategies have been designed and implemented, which are applicable to color images and video sequences. The design of these algorithms has the purpose of extracting spatial and spatio-temporal features from static and dynamic hand gestures, in order to identify them in a robust and reliable way. Finally, a visual database containing the necessary vocabulary of gestures for interacting with the computer has been created.
