Classifying color textures under varying illumination sources remains challenging. To address this issue, this paper introduces a new descriptor for color texture classification, which is robust to changes in the scene illumination. The proposed descriptor, named Color Intensity Local Mapped Pattern (CILMP), incorporates relevant information about the color and texture patterns from the image i...

Robust ∞ H fault-tolerant control against actuator and sensor failures for a class of uncertain descriptor systems via dynamical compensators is investigated. Based on ∞ H theory in descriptor systems, a method of designing dynamical compensators is presented. The dynamical compensator guarantees that the resultant closed-loop system is regular, impulse-free and stable, furthermore, it maintain...

In these days, multimedia data is transmitted and processed in compressed format. Due to the decoding procedure and filtering for edge detection, the feature extraction process of MPEG-7 Edge Histogram Descriptor is time-consuming as well as computationally expensive. To improve efficiency of compressed image retrieval, we propose a new edge histogram generation algorithm in DCT domain in this ...

It is reasonable to believe that the hand movements performed to write words are different from the types of movements performed to draw symbols. Inspired by the models that describe handwriting as a system of coupled oscillations, we believe that the different behaviours, corresponding to text, symbols, or others, present distinguished frequential patterns. Therefore, we propose a descriptor c...

The typical representation of structures (a.k.a. records) includes a header and type descriptor that are a considerable overhead when the structures have few fields and the program allocates a large number of them. We propose structure vectors that group many structures of the same type, removing the need for a header and type descriptor for each contained structure. This paper describes our im...

This paper introduces a design for the taxonomical representation of participants’ instantial meaningmaking, as the basis for providing a measure of ambiguity and contestation. We use hyponymy and meronymy as the basis for our taxonomies and adopt the System Network formalism as the basis for their representation. We achieve an integration of transcript and taxonomy using an XML based ‘satellit...

Recently, with the construction of digital libraries, the management of the large multimedia databases becomes an important issue. Unfortunately, traditional keyword searching techniques are not always effective for multimedia information. Thus, computer science has make incredible progress in retrieval of multimedia data based on image content. However, most of retrieval systems are focus on t...

The partitioning of 29 small organic probes in a PEG-2000/(NH4)2SO4 biphasic system was investigated using a quantitative structure-property relationship (QSPR) approach. A three-descriptor equation with the squared correlation coefficient (R2) of 0.97 for the partition coefficient (log D) was obtained. All descriptors were derived solely from the chemical structure of the compounds. Using the ...

The output-feedback control problem is solved for continuous-time, linear, retarded and neutral type systems. A delay-dependent solution is obtained in terms of linear matrix inequalities (LMIs) by using a descriptor model transformation of the system and by applying Park’s inequality for bounding cross terms. A state-feedback solution is derived for systems with polytopic parameter uncertainti...

Numerically reliable state space algorithms are proposed for computing the following stable coprime factorizations of rational matrices: 1) factorizations with least order denominators; 2) factorizations with inner denominators; and 3) factorizations with proper stable factors. The new algorithms are based on a recursive generalized Schur algorithm for pole assignment. They are generally applic...
