We propose a coupled hidden Markov model (CHMM) approach to video-realistic speech animation, which realizes realistic facial animations driven by speaker independent continuous speech. Different from hidden Markov model (HMM)-based animation approaches that use a singlestate chain, we use CHMMs to explicitly model the subtle characteristics of audio–visual speech, e.g., the asynchrony, tempora...

This study has aimed to compare the effects of two types of form-focused instruction, i.e. de-contextualized focus-on-forms instruction versus meaning-centered contextualized focus-on-form instruction, on the development of grammatical knowledge of Iranian high-school students. Two groups of male high-school first graders participated in this study.  One group was taught through de-contextualiz...

Abstract This study aimed to shed light on young Iranian EFL students’ oral proficiency improvement through explicit instruction of formulaic sequences (FSs). This pretest-posttest quasi experimental study was conducted in a bilingual school in Shahrekord, Iran. Accordingly, based on ACTFL OPI test, two groups of low intermediate students with age range of 11 to 12 were chosen to be assigned as...

This study investigates and compares the efficacy of differentiated instruction and traditional-based instruction on enhancing Iranian students’ reading comprehension. Eight elementary, intermediate, and advanced classrooms from 1 language institute were chosen, and based on their performance on the pretests were further divided into 4 control and 4 treatment groups. Flexible grouping, tiered i...

Facial animation details like wrinkles or bulges are very useful for the analysis and the interpretation of facial emotions and expressions. However, outfitting a virtual face with expression details for real-time applications is a difficult task. In this paper, we propose a mono-camera acquisition technique of facial animation details and a technique which add a wrinkle map layer (fine-scale a...

BACKGROUND Ever since Dr. John Snow (1813-1854) used a case map to identify water well as the source of a cholera outbreak in London in the 1800s, the use of spatio-temporal maps have become vital tools in a wide range of disease mapping and control initiatives. The increasing use of spatio-temporal maps in these life-threatening sectors warrants that they are accurate, and easy to interpret to...

The present study investigated comparatively the impact of two types of input enhancement (i.e. textual vs. compound enhancement) on developing grammar ability in Iranian EFL setting. Sixty-five female secondary high school students were selected as a homogenous sample out of about a 100-member population based on Nelson language proficiency test. Then, their grammar ability was measured based ...

Web-Based Instruction, Individual Differences, System Features. Abstract: In this paper, we describe and propose a web based instruction (WBI) program. The purposes of this research were to develop the Web-Based Instruction model using Social Media Application to enhance Knowledge Management skills. concerning the faculty's participation in developing and teaching Web-based courses may lead to ...
