High-speed photography of the development of microdamage in trabecular bone during compression

The mechanical properties of healthy and diseased bone tissue were extensively studied in mechanical tests. Most of this research was motivated by the immense costs of health care and social impacts due to osteoporosis in post-menopausal women and the aged ...

Dynamic Texture on Fixed-Point Architectures

Sabine Süsstrunk, Luciano Sbaiz, Roberto Costantini

Dynamic textures are sequences of images showing temporal regularity; they can be found in videos representing smoke, flames, flowing water, or moving grass, for instance. Recently, one method based on linear dynamic system theory was proposed to synthesiz ...

Directionlets

Vladan Velisavljevic

Efficient representation of geometrical information in images is very important in many image processing areas, including compression, denoising and feature extraction. However, the design of transforms that can capture these geometrical features and repre ...

On the Use of Masking Models for Image and Audio Watermarking

Justin Picard, Arnaud Robert

In most watermarking systems, masking models, inherited from data compression algorithms, are used to preserve fidelity by controlling the perceived distortion resulting from adding the watermark to the original signal. So far, little attention has been pa ...

Efficient Compressed Domain Target Image Search and Retrieval

Pierre-André Farine, Michael Ansorge

In this paper we introduce a low complexity and accurate technique for target image search and retrieval. This method, which oper- ates directly in the compressed JPEG domain, addresses two of the CBIR challenges stated by The Benchathlon Network regarding ...

Sparse Approximation Using M-Term Pursuits with Applications to Image and Video Compression

Pascal Frossard, Pierre Vandergheynst, Adel Rahmoune

This paper introduces an algorithm for sparse approximation in redundant dictionaries, called the M-Term Pursuit (MTP), based on the matching pursuit approach (MP). This algorithm decomposes the signal into a linear combination of selected atoms, chosen to ...

A Low Complexity Change Detection Algorithm Operating in the Compressed Domain

Pierre-André Farine, Michael Ansorge

This paper introduces a simple, fast, and efficient algorithm for image change detection in the compressed domain. The proposed technique operates directly on Discrete Cosine Transformed (DCT-ed) data which makes it suitable for processing compressed bitst ...

Identification of Image Variations based on Equivalence Classes

Touradj Ebrahimi

This paper presents a fingerprinting method based on equivalence classes. An equivalence class is composed of a reference image and all its variations (or replicas). For each reference image, a decision function is built. The latter determines if a given i ...

Image Replica Detection based on Support Vector Classifier

Touradj Ebrahimi

In this paper, we propose a technique for image replica detection. By replica, we mean equivalent versions of a given reference image, e.g. after it has undergone operations such as compression, filtering or resizing. Applications of this technique include ...

Practical Cryptography in High Dimensional Tori

Robert Granger, Martijn Stam

At Crypto 2004, van Dijk and Woodruff introduced a new way of using the algebraic tori

T_n

in cryptography, and obtained an asymptotically optimal

n/\phi(n)

savings in bandwidth and storage for a number of cryptographic applications. However, the compu ...
