Human action recognition has drawn much attention in the field of video analysis. In this paper, we develop a human action detection and recognition process based on the tracking of Interest Points (IP) trajectory. A pre-processing step that performs spatio-temporal action detection is proposed. This step uses optical flow along with dense(More)
In this paper, a new color image enhancement technique is proposed. First, input color images are converted to the HSV color space. Then, a new proposed enhancement homomorphic filtering technique is applied on the value component to improve illumination. Finally, a color restoration function is used to overcome the problems of color violation. For the(More)
