Recently, the protection of the ownership information of digital images have received much attentions because illegal copying of digital multimedia has become much easier due to the advance of multimedia technologies. The ownership information is embedded as a watermark into the image for the purpose of asserting the copyright, hence, it should be very robust against various attempts to break or remove...
In this paper, a new method for human detection based on Adaboost is proposed: selecting the proper partial features of human which include Haar features and histograms of gradients with new extraction and combining them to form a structure to detect humans. We analyze the robustness of different part detectors of human and gain better features through experiments. And a new method based on histograms...
This paper proposed a parallel particle filter algorithm with the help of GPU (Graphic Processing Unit) in face tracking. Due to illumination and occlusion problems, face tracking usually does not work stably based on a single cue. Three different visual cues, color histogram, edge orientation histogram and wavelet feature, are integrated under the framework of particle filter to improve the tracking...
This paper proposed a multi-cue based face tracking algorithm with the help of parallel multi-core processing. Due to illumination and occlusion problems, face tracking usually does not work stably based on a single cue. Three different visual cues, color histogram, edge orientation histogram and wavelet feature, are integrated under the framework of particle filter to improve the tracking performance...
