We propose a color-based image descriptor that can be used for image indexing based on high-level semantic concepts. The descriptor is based on Kobayashi’s Color Image Scale, which is a system that includes 130 basic colors combined in 1170 three-color combinations. Each combination is labeled with one of 180 high-level semantic concepts, like ”elegant”, ”romantic”, ”provocative”, etc. Moreover...

This article is focused on analyzing stability and L2 gain properties for switched systems composed of a family of linear discrete-time descriptor subsystems. Concerning descriptor systems, they are also known as singular systems or implicit systems and have high abilities in representing dynamical systems [1, 2]. Since they can preserve physical parameters in the coefficient matrices, and desc...

a r t i c l e i n f o a b s t r a c t Keywords: Saliency Low-rank and sparse analysis Shape feature Structure This paper advocates a novel multi-scale mesh saliency method using the powerful low-rank and sparse analysis in shape feature space. The technical core of our approach is a new shape descriptor that embraces both local geometry information and global structure information in an integra...

Structure-based virtual screening is one of the most important and common computational methods for the identification of predicted hit at the beginning of drug discovery. Pocket recognition and definition is frequently a prerequisite of structure-based virtual screening, reducing the search space of the predicted protein-ligand complex. In this paper, we present an optimal ligand shape descrip...

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...

This paper presents a global analysis framework for determining the availability of data on a virtual processor grid. The data availability information obtained is useful for optimizing communication when generating SPMD programs for distributed address-space multi-processors. We introduce a new kind of array section descriptor, called an Available Section Descriptor, which represents the mappi...

This paper considers the robust stability for uncertain fractional-order (FO) descriptor nonlinear systems. A key analysis technique is enabled by proposed a fundamental boundedness lemma, for the first time. It is used for rigorous robust stability analysis of FO systems, especially for Mittag-Leffler stability analysis of FO nonlinear systems. More importantly, how to obtain a more accurate b...
