Title: A New Approach For Hand Gestures Recognition Based on Depth Map Captured by RGB-D Camera
Abstract: This paper presented a new approach for hand gestures recognition based on depth Map captured by an RGB-D Kinect camera. Although this camera provides two types of information ”Depth Map” and ”RGB Image”, only the depth data information was used to analyze and recognize the hand gestures. Given the complexity of this task, we first proposed a new method based on edge detection to eliminate the noise and segment the hand. Then we introduced new descriptors modeling the hand gesture. These features are invariant to scale, rotation and translation. Our approach was applied on French sign language alphabet to show its effectiveness and evaluate the robustness of the proposed descriptors. The experimental results clearly show that the proposed system is very satisfactory and able to recognize the French alphabet sign with an accuracy of more than 93%. Our approach was also applied to a public dataset in order to be compared to existing works. The results prove that our system can outperform previous methods using the same dataset.

Title: 2DPCA fractal features and genetic algorithm for efficient face representation and recognition
Abstract: In this article, we present an automatic face recognition system. We show that fractal features obtained from Iterated Function System allow a successful face recognition and outperform the classical approaches. We propose a new fractal feature extraction algorithm based on genetic algorithms to speed up the feature extraction step. In order to capture the more important information that is contained in a face with a few fractal features, we use a bi-dimensional principal component analysis. We have shown with experimental results using two databases as to how the optimal recognition ratio and the recognition time make our system an effective tool for automatic face recognition.

Title: A new approach for digit recognition based on hand gesture analysis
Abstract: We present in this paper a new approach for hand gesture analysis that allows digit recognition. The analysis is based on extracting a set of features from a hand image and then combining them by using an induction graph. The most important features we extract from each image are the fingers locations, their heights and the distance between each pair of fingers. Our approach consists of three steps: (i) Hand detection and localization, (ii) fingers extraction and (iii) features identification and combination to digit recognition. Each input image is assumed to contain only one person, thus we apply a fuzzy classifier to identify the skin pixels. In the finger extraction step, we attempt to remove all the hand components except the fingers, this process is based on the hand anatomy properties. The final step consists on representing histogram of the detected fingers in order to extract features that will be used for digit recognition. The approach is invariant to scale, rotation and translation of the hand. Some experiments have been undertaken to show the effectiveness of the proposed approach.
