: This paper proposes a new watermarking method for detecting image tampering. First, an authentication number is created using a pair of watermark pixels as the coefficients of a ...
We present a novel approach for learning patterns (sub-images) shared by multiple images without prior knowledge about the number and the positions of the patterns in the images. ...
So far global optimization techniques have been developed independently for the tasks of shape matching and image segmentation. In this paper we show that both tasks can in fact b...
We propose a novel approach to shape-based image retrieval that builds upon a similarity criterion which is based on the average point set distance. Compared to traditional techni...
We propose a novel wearable imaging system that can capture omnidirectional movies from the viewpoint of the camera wearer. The imaging system solves the problems of resolution un...
