We propose a robust approach for aligning lecture slides with lecture videos using a combination of Hough transform, optical flow and Gabor analysis. A Markov Decision Process mod...
In this article we proposed an improved SIFT-based object recognition methodology for robot applications. This methodology is employed for implementing a robot-head detection syste...
This paper presents a generalized theoretical framework for designing accurate steerable filters for orientation estimation. We derive necessary properties of orientation estimat...
Many volume filtering operations used for image enhancement, data processing or feature detection can be written in terms of threedimensional convolutions. It is not possible to y...
The symmetrical decomposition is a powerful method to extract features for image recognition. It reveals the significant discriminative information from the mirror image of symmetr...
