Introduction to Computer Vision

Computer assisted instruction during quarantine and computer vision syndrome

Computer vision syndrome (CVS) is a set of visual, ocular, and musculoskeletal symptoms that result from long-term computer use. These symptoms include eyestrain, dry eyes, burning, pain, redness, blurred vision, etc, which increase with the duration of computer use. Currently, with the closure of schools and universities due to the continued COVID19 pandemic many universities have taken the pr...

Human Computer Interaction Using Vision-Based Hand Gesture Recognition

With the rapid emergence of 3D applications and virtual environments in computer systems; the need for a new type of interaction device arises. This is because the traditional devices such as mouse, keyboard, and joystick become inefficient and cumbersome within these virtual environments. In other words, evolution of user interfaces shapes the change in the Human-Computer Interaction (HCI). In...

An Investigation of Structural-Mechanical Properties of Spun-Bonded Non-Woven Using Computer Vision Method

عوامل پیش‌بینی کننده وضعیت ارگونومیک کاربران رایانه بر اساس مدل فرا نظری

Introduction: Long-term work with computer can lead to damage of vision and musculoskeletal disorder on the computer users. The aim of this study was to determine the predictors of ergonomic computer users based on the Trans theoretical model of computer users working in Baqiyatallah hospital (Aj) in Tehran. Material and Methods: This descriptive study - an analysis on 102 computer users wit...

A Fast, Robust, Automatic Blink Detector

Introduction “Blink” is defined as closing and opening of the eyes in a small duration of time. In this study, we aimed to introduce a fast, robust, vision-based approach for blink detection. Materials and Methods This approach consists of two steps. In the first step, the subject’s face is localized every second and with the first blink, the system detects the eye’s location and creates an ope...
