Nowadays, with the development of Internet technology and the improvement of safety awareness, image encryption technique has become very important, especially for color image encryption. The direction of research is focused on the RGB color space. There are few researches in other color spaces, such as HSV, L∗a∗b∗, YCbCr. In this paper, we propose a color image encryption method in YCbCr color space...
In this paper, we propose a novel method for image based object relighting through patch match warping and color transfer. According to our method, a pair of reference object images (A and B), without any knowledge of the 3D geometry or material information of the input object image, are needed. The input image has similar illumination condition as that of the reference image A. The reference image...
The purpose of this paper is to provide reference for the design of more practical and efficient non-distributed flight reference(NDFR) symbology of helmet-mounted display(HMD) by comparing four kinds of attitude symbologys (include climb-dive angle and roll). The flight references were NDFR, NDFR-R (NDFR plus zero-degree Climb-Dive Angle CDA reference), NDFR-M (mini-arc NDFR) and ANDFR(Advanced NDFR)...
Object tracking algorithm using modified Particle filter in low frame rate (LFR) video is proposed in this paper, which the object moving significantly and randomly between consecutive frames in the low frame rate situation. Traditionally, Particle filtering use motion transitions to model the movement of the target. However, in object tracking with low frame rate sequences, it is very difficult to...
Robust real-time tracking of non-rigid objects is a challenging task. Color is a powerful feature for tracking deformable objects in image sequences with complex backgrounds. Color distribution is applied, as it is robust to partial occlusion, is rotation and scale invariant and computationally efficient. Particle filter has been proven very successful for non-linear and non-Gaussian estimation tracking...
