In this paper, we propose a supervised approach to find out the probabilistic mapping of semantic contours in color images. We prepare a new color image modifying the RGB color planes to incorporate reasonable within-object contrasts in all the color planes. Color gradient based features are then extracted from this altered version of color image. Next, multiple support vector machines (SVMs) are...
In this paper, we described making process of interactional promotion content using augmented reality technology. I used QualComm's Augmented Reality (QCAR) technology to make promotion content. Because QCAR had presented button function to manipulate augmented object, I could have added interactional factor to the content. Also, I added game content to the augmenting object because QCAR library could...
Electronic book is usually used for users who want to read the text book with multimedia contents like video and audio. Many electronic books have been proposed with new interactive technologies such as spectacular multimedia effect, but these books lack in analog sensitivity and have only one way-based information interaction, and consequently those are inefficient for users. To solve the problem,...
In this paper, we propose how to recognize upper-body poses using depth image based cylindrical coordinate system. In order to recognize the pose, we configure the cylindrical coordinate system belong to body features and the distance which is configured from camera to center of body using the pose candidate images. And we extract vectors of the features using depth information which are presented...
Robust and real time moving object tracking is a tricky job in computer vision problems. Particle filtering has been proven very successful for non-Gaussian and non-linear estimation problems. In this paper, we first try to develop a color based particle filter. In this approach, the object tracking system relies on the deterministic search of window, whose color content matches a reference histogram...
In this paper, we propose an approach to calculate optical flow by using dynamic graph cuts framework. We use several good ingredients to estimate optical flow. We combine occlusion model for visual correspondence problem (V. Kolmogorov and R. Zabih, 2001) and illumination invariant optical flow (D. Freedman and M.W. Turek, 2005) to achieve robustness given large occlusion and illumination changes...
