A new method for hand gesture recognition that is based on a hand gesture fitting procedure via a new Self-Growing and Self-Organized Neural Gas (SGONG) network is proposed. Initially, the region of the hand is detected by applying a color segmentation technique based on a skin color filtering procedure in the YCbCr color space. Then, the SGONG network is applied on the hand area so as to appro...

Abstract This paper presents a novel face detection and gender classification strategy in color images under nonuniform background. This is done by detecting the human skin regions in image given and detecting facial features based on the measurements in pixels. The proposed algorithm converts the RGB image into the YCbCr color space to detect the skin regions in the facial image. But in order ...

Face detection is a very challenging and interesting problem. In this paper, a new scheme for detection of multiple faces using Haar wavelet packet decomposition based on quantized skin color region merging under unconstrained scene conditions is presented. Color clustering and filtering using approximations of the YCbCr and HSV skin color subspaces are applied on the original image by providin...

This paper describes the design and construction of a prototype for embedded face detection and recognition algorithms. The test-bed is called the PITS (Portable Interactive Terrorist Identification System). It makes use of a hand-held device called the Sharp Zaurus. The embedded device has a processor, camera, color display, and wireless networking. This system is different from existing syste...

In this paper we propose a system for dynamic hand gesture recognition of Arabic Sign Language. The proposed system takes the dynamic gesture (video stream) as input, extracts hand area and computes hand motion features, then uses these features to recognize the gesture. The system identifies the hand blob using YCbCr color space to detect skin color of hand. The system classifies the input pat...

A series of computer vision-based fire detection algorithms is proposed in this paper. These algorithms can be used in parallel with conventional fire detection systems to reduce false alarms. They can also be deployed as a standalone system to detect fire combined with a video acquisition device. This paper chiefly discussed the segmentation problem. It adopted the L*a*b*, YCbCr color space an...

Four novel color Local Binary Pattern (LBP) descriptors are presented in this chapter for scene image and image texture classification with applications to image search and retrieval. Specifically, the first color LBP descriptor, the oRGB-LBP descriptor, is derived by concatenating the LBP features of the component images in an opponent color space — the oRGB color space. The other three color ...

This paper presents an approach for determining the presence of people in a still image. The approach starts with the segmentation of skin areas in the images using the YCbCr color space and a set of experimentally defined thresholds. The detected skin areas are then grouped into body part candidate regions. Regions that are too small (typically smaller than 5x5) are discarded. A simple heurist...

The success of international standardization of image compression techniques resulted in a consequent increase in the number of images and videos in various media publications, web publications, etc. There was a need for a system to classify and manage the content of those compressed images and videos. The visual descriptors describe characteristics such as color, shape, texture, motion, etc. C...
