Rotation invariant texture characterization and retrieval using steerable wavelet-domain hidden Markov models

Martin Vetterli, Minh Do

We present a new statistical model for characterizing texture images based on wavelet-domain hidden Markov models. With a small number of parameters, the new model captures both the subband marginal distributions and the dependencies across scales and orie ...

Algorithms for Video Structuring

Daniel Gatica-Perez, Jean-Marc Odobez

Video structuring aims at automatically finding structure in a video sequence. Occupying a key-position within video analysis, it is a fundamental step for quality indexing and browsing. As a low level video analysis, video structuring can be seen as a ser ...

3-D Reconstruction of DNA Filaments from Stereo Cryo-Electron Micrographs

Michaël Unser, Thierry Blu, Mathews Jacob

We propose an algorithm for the 3-D reconstruction of DNA filaments from a pair of stereo cryo-electron micrographs. The underlying principle is to specify a 3-D model of a filament—described as a spline curve—and to fit it to the 2-D data using a snake-li ...

Color Encodings for Image Databases

Sabine Süsstrunk

There are a number of color encoding standards that have lately been developed ant are being proposed to the imaging community for different encoding steps in the color imaging workflow, optimized for different purposes. In this paper, their applicability ...

Design and Implementation of a Universal Multimedia Access Environment

Touradj Ebrahimi, David Marimon Sanjuan

The objective of Universal Multimedia Access (UMA) is to permit any user equipped with whatever device the access to multimedia information. To handle the problems of UMA, two different approaches are commonly used: store variations of the same content and ...

Joint Textual And Visual Cues For Retrieving Images Using Latent Semantic Indexing

Martin Vetterli, Serge Ayer, Zoran Pecenovic

In this article we present a novel approach of integrating textual and visual descriptors of images in a uniﬁed retrieval structure. The methodology, inspired from text retrieval and information ﬁltering is based on Latent Semantic Indexing (LS1). ...

Color Strategies for Image Databases

Sabine Süsstrunk

In this paper, color encoding strategies for different image database applications are discussed. The color image workflow is examined in detail, and master and derivative file encoding strategies are outlined in relation to capture, maintenance, and deplo ...

Dynamic overview techniques for image retrieval

Pearl Pu Faltings

One difficulty often overlooked in information retrieval systems is that search criteria themselves are often poorly defined. People describe their information needs in many different ways and frequently change their goals depending on the current results ...

Integrated browsing and searching of large image collections

Martin Vetterli, Pearl Pu Faltings, Minh Do

Current image retrieval systems offer either an exploratory search method through browsing and navigation or a direct search method based on specific queries. Combining both of these methods in a uniform framework allows users to formulate queries more nat ...

Indexing spoken audio by LSA and SOMs

This paper presents an indexing system for spoken audio documents. The framework is indexing and retrieval of broadcast news. The proposed indexing system applies latent semantic analysis (LSA) and self-organizing maps (SOM) to map the documents into a sem ...
