Active contour (snake) approaches have been proved to be efficient tools to extract object boundary precisely. One drawback of these methods is that state-of-the-art snake algorit...
A drawback of most watermarking techniques is the need for some additional information in order to retrieve the watermark. Additionally, the robustness of the watermark decreases ...
Standard methods for image interpolation are based on smoothly fitting the image intensity surface. Recent edgedirected interpolation methods add limited geometric information (ed...
We present a method for extracting contours from digital images using techniques from computational geometry. Our approach is different from traditional pixelbased methods in imag...
This paper proposes a visual representation named scene tunnel to archive and visualize urban scenes for Internet based virtual tour. We scan cityscapes using multiple cameras on ...
