A bst ract : A delay2dependent Hinfinity control for descriptor systems with a state2delay is investigated. The purpose of the problem is to design a linear memoryless state2feedback controller such that the resulting closed2loop system is regular ,impulse free and stable with an H-infinity norm bound. Firstly , a delay2dependent bounded real lemma (B RL) of the time2delay descriptor systems is...

In this paper we improve the histogram of oriented gradients (HOG), a core descriptor of state-of-the-art object detection, by the use of higher-level information coming from image segmentation. The idea is to re-weight the descriptor while computing it without increasing its size. The benefits of the proposal are two-fold: (i) to improve the performance of the detector by enriching the descrip...

Four novel color Local Binary Pattern (LBP) descriptors are presented in this chapter for scene image and image texture classification with applications to image search and retrieval. Specifically, the first color LBP descriptor, the oRGB-LBP descriptor, is derived by concatenating the LBP features of the component images in an opponent color space — the oRGB color space. The other three color ...

-The paper considers the problems of state estimation, unknown input and measurement disturbance reconstruction for a class of Lipschitz nonlinear system. By taking the measurement disturbance vector as an extended state vector, the original system is transformed into an augmented descriptor system. For the descriptor system, the necessary and sufficient condition of the existence of the unknow...

Due to the expension of High Dynamic Range (HDR) imaging applications into various aspects daily life, an efficient retrieval system, tailored this type data, has become a pressing challenge. In paper, reliability Convolutional Neural Networks (CNN) descriptor and its investigation for HDR image are studied. The main idea consists in exploring use CNN determine descriptor. Specifically, Percept...

Analyzing the order of unobservable impulse in descriptor system leads to a new testing criterion for impulse observability, both the statement and the proof of which use only the original system data.

In this paper we consider models for noncausal processes consisting of discrete-time descriptor dynamics and boundary conditions on the values of the process at the two ends of the interval on which the process is defined. We discuss the general solution and well-posedness of systems of this type and then apply the method of complementary processes to obtain a specification of the optimal smoot...

Human action recognition from videos is a challenging machine vision task with multiple important application domains, such as humanrobot/machine interaction, interactive entertainment, multimedia information retrieval, and surveillance. In this paper, we present a novel approach to human action recognition from 3D skeleton sequences extracted from depth data. We use the covariance matrix for s...
