TL;DR: Experimental results show that the proposed method to analyzing the head pose and the facial expression of a human face from a single image is robust and has a high percentage of convergency, and thus prove the feasibility of the proposed approach.

TL;DR: The two issues of art image creation and data hiding are integrated into one and solved by a single approach in this study, which proposes an automatic method for generating a new type of computer art, called stained glass image, which imitates the stained-glass window picture.

TL;DR: 3D vision-based methods for security monitoring around a video surveillance car using a pair of newly-designed two-camera omni-directional imaging devices affixed on the car roof are proposed and a new analytic technique of 3D data acquisition using the camera system based on the use of the pano-mapping method and the rotational invariance property of the Omni-camera is proposed.

TL;DR: In this article, a method for protecting the content of vector graphics formats is presented, where a first vector graphics is scrambled to generate a second vector graphics, and then a plurality of pixel samplings are performed by the first vector images which generating at least a recovery information object according to a predetermined graphics.
