Image template detection is usually a very important halfway step for a computational vision algorithm. A recently proposed approach for it involves the use of discriminative filt...
In this contribution we present an algorithm for spatial error concealment of lost image data caused by transmission of images in error prone environments. The surrounding correct...
In this paper we propose a novel, adaptive method for motion compensated 3D wavelet transformation (MC 3D-DWT) of video. The proposed method overcomes problems of ghosting and non...
We investigate the implications of the conventional "t+2D" MC 3D-DWT structure for spatial scalability, and propose a more exible "2D+t+2D" structure. An initi...
An increasing interest in the soft hashing problem has been witnessed in recent times. Techniques implementing soft hashing intend to mirror the behaviour of cryptographic hashing...
A robust method of camera response function estimation, using pictures taken by differently illuminating the same subject matter, is presented. The method solves for the response ...
The paper proposes a blind spread spectrum watermarking scheme where watermark information is embedded redundantly in the multilevel wavelet coefficients of the cover image. It ha...
In this paper we propose a fast motion estimation technique that works in the wavelet domain. The computational cost of the algorithm turns out to be proportional to the linear si...
