To address the problem of visual content description, two Description Schemes (DSs) developed within the context of a European ACTS project known as DICEMAN, are presented. The DSs, designed based on an analogy with well-known tools for document description, describe both the structure and semantics of still images and video sequences. The overall structure of both DSs including the various sub...
Scarlet (Solanum aethiopicum) and gboma (S. macrocarpon) eggplants are major vegetable crops in sub-Saharan Africa. Together with their respective wild ancestors (S. anguivi and S. dasyphyllum) and intermediate cultivated-wild forms they constitute the so-called scarlet and gboma eggplant complexes. We used conventional descriptors and the high-throughput phenomics tool Tomato Analyzer for char...
We present spatio-temporal feature descriptors that can be inferred from video and used as building blocks in action recognition systems. They capture the evolution of “elementary action elements” under a set of assumptions on the image-formation model and are designed to be insensitive to nuisance variability (absolute position, contrast), while retaining discriminative statistics due to the f...
Audio descriptor analysis in real-time or in batch is increasingly important for advanced sound processing, synthesis, and research, often using a relaxed-real-time approach. Existing approaches mostly lack either modularity or flexibility, since the design of an efficient modular descriptor analysis framework for commonly used real-time environments is non-trivial. We first lay out the require...
Rice is the most important food security crop in Asia. Information on its seasonal extent forms part of the national accounting of many Asian countries. Synthetic Aperture Radar (SAR) imagery is highly suitable for detecting lowland rice, especially in tropical and subtropical regions, where pervasive cloud cover in the rainy seasons precludes the use of optical imagery. Here, we present a simp...
background: patients with bleeding disorders are frequently infected with hepatitis c virus (hcv). there are few reports on the effect of standard interferon in these patients and no published report on pegylated interferon. the aim of this study was to compare pegylated interferon alpha-2a and standard interferon alpha with ribavirin in patients with bleeding disorders and chronic hcv infectio...
Problem statement: This study investigated zero crossing features and selected MPEG-7 audio descriptors for environment sound recognition applications such as audio forensics. Approach: The study implemented several experiments focusing on the problems of environment recognition from audio particularly for forensic applications. Results: It was investigated the effect of the temporal zero cross...
The use of vision based algorithms in minimally invasive surgery has attracted significant attention in recent years due to its potential in providing in situ 3D tissue deformation recovery for intra-operative surgical guidance and robotic navigation. Thus far, a large number of feature descriptors have been proposed in computer vision but direct application of these techniques to minimally inv...
Abstract. We check-out a set of statistical network descriptors for classification of various vascular networks generated by model of Tumour Induced Angiogenesis. In the model two spatio-temporal scales representing global behaviour of vascular network and local processes in surround tissue are clearly separated. The grid of cellular automata (CA) corresponds to both healthy and cancerous tissu...
