This article deals with the problem of recognition of semi-structured documents image. The aim is to detect a document and to extract the region of interest containing it. Initially, an exemple of document is given by the user and a set of interest points are extracted from this query image. In a second step, a set of interest points is extracted from each image to analyse and is matched with t...

In this paper, we present a region of interest encoding system for video conference applications. We will utilize the fact that the main focus in a typical video conference lies upon the participating persons in order to save bit-rate in less interesting parts of the video. A Viola-Jones face detector will be used to detect the regions of interest. Once a region of interest has been detected it...

periodic noises are unwished and spurious signals that create repetitive pattern on images and decreased the visual quality. firstly, this paper investigates various methods for reducing the effects of the periodic noise in digital images. then an adaptive optimum notch filter is proposed. in the proposed method, the regions of noise frequencies are determined by analyzing the spectral of noisy...

Human action recognition has a wide range of promising applications like video surveillance, intelligent interface, and video retrieval. The objective of this project is to recognize and annotate different human activities present in digital videos taken from both constrained and unconstrained environment. This work extended the use of the techniques existing in object recognition in 2D images ...

In this paper, a methodology for ROI extraction in INDT using multi-resolution analysis is proposed. Complementary, both local procedures Harris operator and gradient direction are used. The proposed methodology is tested using three CFRP specimens having complex shapes and defects at different depths. Besides, another two specimens are considered, which are made of PlexiglasTM and aluminum wit...

In the current context of increased surveillance and security, more sophisticated surveillance systems are needed. One idea relies on the use of pairs of video (visible spectrum) and thermal infrared (IR) cameras located around premises of interest. To automate the system, a dedicated image processing approach is required, which is described in the paper. The first step in the proposed study is...

This paper presents a systematic methodology to analyze displacement metrics to be used in recognizing facial expressions with the help of FAP or landmarks on a face particularly on the mouth, nose tip and eye and eye brows. The proposed system tries to automatically perform human face detection, feature point extraction for the further purpose of facial expression recognition stably and robust...
