Curiosity is a key element of human development, driving us to explore spontaneously novel objects, activities and environments [1]. Curiosity-driven exploration strategies permit us to interact, learn and evolve quickly in an open ended world. It is thus an important challenge to understand the fundamental mechanisms of spontaneous exploration and curiosity in humans.
Cognitive development is dynamic and opportunistic, following developmental pathways [1]: The same skill can develop in many different ways, depending on the chains of events and opportunities that are presented to the learning individual. What factors shape these developmental pathways?
This paper presents a fresh food recognition system that utilizes the feature fusion extracted from food images captured from optical fibers embedded inside a chopping board. We exploit both local and global features including color, SURF and shape for image representation. In addition, we propose cost-based schemes for feature matching and the Borda count method for feature fusion. An experiment...
This work presents a proposal for a quality measure that focuses on the user's subjective quality of experience. The challenges are to define factors that influence quality and to link up the quality of experience with the technical realization process. The advantages of interlinking the quality of experience with the quality of service are to profit the technical realization process in order to allow...
The thermal conductivity of sintered porous pastes of metals is modelled, based on an analytical and a numerical approach. The first method arises from the differential effective medium theory and considers the air voids as ellipsoidal pores of different sizes, while second one is based on the finite element method to analyse the scanning-electron-microscope images of the paste cross sections. It...
According to the purpose of adapting the characteristics of music schools to the music team construction and development, this paper puts forward the concept of social fitness in music higher education from the achievable characteristics of music schools, demand characteristics of music education and fitness of education system and probes further into fitness, quantity between music education and...
Today, gesture analysis lacks of global models able to characterize motion expressivity and its communicational character. In this paper, we propose a set of new gesture descriptors inspired from Laban Movement Analysis (LMA) and based on 3D body trajectories. We test our descriptors ability to characterize human actions in a machine learning framework (with SVM and different random forest techniques)...
Stereo matching remains a difficult vision problem for the image noise, textureless regions, depth discontinuities and occlusions. This paper presents a novel adaptive window stereo matching algorithm based on seed voting to solve these ill-posed problems. There are three key contributions in this paper: combining color and gradient as conditional tags to restrain initial window size for further adaptively...
The major challenge of video surveillance systems is the automated detection and interpretation of events of interest. In case of an abnormal event taking place, an alert should be delivered. Generally, a video surveillance system's framework combines three main phases: moving objects extraction, moving objects classification and tracking, scenario recognition. The last stage depends on the aimed...
Qualitative Mapping(QM) is the basis of Property Theory, by which Conversion Degree Functions are induced. Furtherly Inverse Conversion Degree Functions are proposed used to convert qualitative description into quantitative value for some attributes of objects according to the degree to which the qualitative description belongs. Finally Qualitative Membership Degree Matrix based on the proportion...
Indian stone inscriptions play an important role in the reconstruction of the history of India. Kannada is considered the oldest language next to Sanskrit, Prakrit, and Tamil. According to linguists Tamil and Kannada branched off simultaneously from the Dravidian language of South India before the Christian Era. Indian epigraphy becomes more widespread over the 1st millennium, engraved on the faces...
Covering is an important form of data, and covering-based rough sets provide an effective tool to deal with this data. In this paper, we use bipartite graphs to study covering-based rough sets. Firstly, a bipartite graph is constructed through a covering, named bipartite graph associated with a covering. According to a bipartite graph associated with a covering, two equivalent representations of a...
This paper describes the design of a three-legged reconfigurable spherical robot II. The reconfigurable spherical robot II is designed with the ability to transform from a spherical shape into a configuration of two interconnected hemispheres and three legs which are kept inside the shells can be extended to provide mobility on ground. The reconfigurable spherical robot II introduced a new method...
This paper proposes distance-based adaptive formation control laws for the leader-follower system. The developed controller makes all the agents maintain the formation group and move with a constant reference velocity in a plane. It is assumed that there are one leading and two following agents. The leading agent knows the reference velocity whereas the follower does not know the velocity of other...
Random projection is a tried-and-true technique in signal processing for reducing sensing complexity while maintaining acceptable performance of downstream processing tasks. In this paper, we investigate random linear projection of point clouds followed by topo-logical data analysis for computing persistence diagrams and Betti numbers. In this first empirical study of its kind in the literature, we...
The Histogram PMHT is a parametric track-before-detect method that has good detection performance and low computation complexity. However, the method assumes a known clutter distribution. This paper introduces a method for learning a non-uniform clutter map where the map is represented as a mixture of parameterised components. The modified Histogram PMHT is compared with the uniform clutter model...
In this paper, we introduce a method for finger-spelling recognition system. The objective is to help the deaf or non-vocal persons to improve their skills on the finger-spelling. Many researches in this field have proposed methods mostly based on hand posture estimation techniques. We propose an alternative flexible method based on fuzzy finger shape and hand appearance analysis. By using depth image,...
In order to address the efficient issue of the topological shape optimization problem, this paper presents a parametric level set method for the problem of continuum structures by using the Radial Basis Functions (RBFs). The level set-based method is introduced to implicitly represent the free boundary of a structure. To evolve the level set front, the Wu's compactly supported radial basis function...
In this paper, we present a robust approach of automatic detection and recognition of road signs in national roads, starting from the images resulting from a video stream taken by a camera embarked on a vehicle. Our approach is composed of three main phases: the first phase is to extract video stream images containing a circle or a triangle. This extraction is performed respectively by Hough transformation...
The most widely used in the field of visual object recognition descriptive features are shape based features. Identify objects in the image, contour and region shape descriptors based on two main topics to be examined. In order to describe objects with lesser number of descriptors, linear or cubic curves are fitted to the contours of the objects. The end points of these finite length curves are usually...
