Low bit-rate compression of omnidirectional images

Pascal Frossard, Ivana Tosic

Omnidirectional images represent a special type of images that are captured by vision sensors with a 360-degree field of view. This work targets the compression of such images by taking into account their particular geometry. We first map omnidirectional i ...

Shape distortions and Gestalt grouping in anorthoscopic perception

Michael Herzog

When a figure moves behind a stationary narrow slit, observers often report seeing the figure as a whole, a phenomenon called slit viewing or anorthoscopic perception. Interestingly, in slit viewing, the figure is perceived compressed along the axis of mot ...

Bit Rate Allocation for Disparity Estimation from Compressed Images

Pascal Frossard, Vijayaraghavan Thirumalai

This paper presents a novel rate allocation scheme to compute the 3D structure of the scene from compressed stereo images, captured by the distributed vision sensor networks. The images captured at different view points are encoded independently with a bal ...

An Asynchronous Programmable Parallel 2-D Image Filter CMOS IC Based on the Gilbert Multiplier

Rafal Tomasz Dlugosz

A novel analogue power-efficient 2-D programmable finite impulse response image filter is proposed. This solution is based on the current-mode Gilbert-vector-multiplier operating in the weak inversion region, which allows for ultra low power operation. The ...

Subjective evaluation of JPEG XR image compression

Touradj Ebrahimi, Francesca De Simone, Lutz Goldmann

In this paper a procedure for subjective evaluation of the new JPEG XR codec for compression of still pictures is described in details. The new algorithm has been compared to the existing JPEG and JPEG 2000 standards when considering compression of high re ...

A comparative study of color image compression standards using perceptually driven quality metrics

Touradj Ebrahimi, Francesca De Simone, Frédéric Dufaux, Michael Ansorge

The task of comparing the performance of different codecs is strictly related to the research in the field of objective quality metrics. Even if several objective quality metrics have been proposed in literature, the lack of standardization in the field of ...

Cooperative media streaming using adaptive network compression

Tom Larsen

Media content distribution constitutes a growing share of the services on the Internet. Two distinct distribution approaches used today are Layered Coding (LC) and Multiple Description Coding (MDC). Current wireless connection technologies, e.g. Wimax, hav ...

Lower Bounds on the Rate-Distortion Function of Individual LDGM Codes

Rüdiger Urbanke, Shrinivas Kudekar

We consider lossy compression of a binary symmetric source by means of a low-density generator-matrix code. We derive two lower bounds on the rate distortion function which are valid for any low-density generator-matrix code with a given node degree distri ...

Salient Region Detection and Segmentation

Sabine Süsstrunk, Radhakrishna Achanta, Francisco Estrada, Patricia Wils

Detection of salient image regions is useful for applications like image segmentation, adaptive compression, and region-based image retrieval. In this paper we present a novel method to determine salient regions in images using low-level features of lumina ...

On the Heegard-Berger/Kaspi problem with decoder cooperation

Dinkar Vasudevan

We consider decoder cooperation in the Heegard-Berger/Kaspi problem. The encoder sends a common description of a source to two decoders, one of which has side information. Cooperation between the two decoders is of the form of a limited capacity link from ...
