The size of remotely sensed imagery continues to grow at rapid rates with the advent of new high resolution sensors. Remote sensing images contain huge amount of geographical information that reflects the complexity of geographical features and spatial structures. Image mosaics covering large geographical regions at multiple resolutions are also becoming more prevalent. New techniques are needed to...
This paper introduces a new hand gesture recognition technique to recognize Arabic sign language alphabet and converts it into voice correspondences to enable Arabian deaf people to interact with normal people. The proposed technique captures a color image for the hand gesture and converts it into YCbCr color space that provides an efficient and accurate way to extract skin regions from colored images...
In this paper, we propose a rule-based system for semantically understanding and analyzing the motion of the trajectories of the human activity. The proposed system can be used as a preprocessing phase for enhancing the object detection process. Detected trajectories are classified into three categories; normal, semi-normal and abnormal trajectories according to the distances between their adjacent...
