Static Gesture Recognition Combining Graph and Appearance Features

Author 1: Marimpis Avraam

In this paper we propose the combination of graph-based characteristics and appearance-based descriptors such as detected edges for modeling static gestures. Initially we convolve the original image with a Gaussian kernel and blur the image. Canny edges are then extracted. The blurring is performed in order to enhance some characteristics… Read full abstract & cite →

Human Gait Gender Classification using 3D Discrete Wavelet Transform Feature Extraction

Author 1: Kohei Arai Author 2: Rosa Andrie Asmara

Feature extraction for gait recognition has been created widely. The ancestor for this task is divided into two parts, model based and free-model based. Model-based approaches obtain a set of static or dynamic skeleton parameters via modeling or tracking body components such as limbs, legs, arms and thighs. Model-free approaches… Read full abstract & cite →

Method for Traffic Flow Estimation using On-dashboard Camera Image

Author 1: Kohei Arai Author 2: Steven Ray Sentinuwo

This paper presents the method to estimate the traffic flow on the urban roadway by using car’s on-dashboard camera image. The system described, shows something new which utilizes only road traffic photo images to get the information about urban roadway traffic flow automatically. Read full abstract & cite →

Predicting Quality of Answer in Collaborative Question Answer Learning

Author 1: Kohei Arai Author 2: ANIK Nur Handayani

Studies over the years shown that students had actively and more interactively involved in a classroom discussion to gain their knowledge. By posting questions for other participants to answer, students could obtain several answers to their question. The problem is sometimes the answer chosen by student as the best answer… Read full abstract & cite →

Using Unlabeled Data to Improve Inductive Models by Incorporating Transductive Models

Author 1: ShengJun Cheng Author 2: Jiafeng Liu Author 3: XiangLong Tang

This paper shows how to use labeled and unlabeled data to improve inductive models with the help of transductivemodels.We proposed a solution for the self-training scenario. Self- training is an effective semi-supervised wrapper method which can generalize any type of supervised inductive model to the semi-supervised settings. it iteratively refines… Read full abstract & cite →

Migration Dynamics in Artificial Agent Societies

Author 1: Harjot Kaur Author 2: Karanjeet Singh Kahlon Author 3: Rajinder Singh Virk

An Artificial Agent Society can be defined as a collection of agents interacting with each other for some purpose and/or inhabiting a specific locality, possibly in accordance to some common norms/rules. These societies are analogous to human and ecological societies, and are an expanding and emerging field in research about… Read full abstract & cite →
