Unsupervised Change Detection using Thin Cloud-Contaminated Landsat Images

YAVARIABDI, Amir | KUSETOĞULLARI, Hüseyin | MENDİ, Engin | KARABATAK, Begüm

In this paper, a novel unsupervised change detection method is proposed to automatically detect changes between two cloud-contaminated Landsat images. To achieve this, firstly, a photometric invariants technique with Stationary Wavelet Transform (SWT) are applied to input images to decrease the influence of cloud and noise artifacts in the change detection process. Then, mean shift image filtering is employed on the sub-band difference images, generated via image differencing technique, to smooth the images. Next, multiple binary change detection masks are obtained by partitioning the pixels i ...Daha fazlası

Monitoring of Miner by RF Signal

SARAY, Tuğba | ÇETİNKAYA, Ali | MENDİ, Engin

Wireless communication technology is spreading rapidly to all areas of our lives. The technology, which has a wide range of applications from radios, intelligent home systems, automation applications to GPS units, was used in monitoring the workers working in mines in this study. Most of the mining area underground mining is risky and the possibility of accident (gas jams, the explosion and dents, etc.) is the area of high. Locating is vital in this line of work when a sudden accident or dent occurred in which the worker will be known and the position of the recovery efforts can be intensified ...Daha fazlası

A Novel Method and Mobile System for Accurate Heart Rate Measurement from Finger and Face

GÖNÜLTAŞ, Emre | DEMİRBAŞÇI, Oğuz | MENDİ, Engin

Heart rate is an important vital indicator which provides information about the rhythm of the heart and helps in diagnosing several heart diseases. As it can be usually determined manually, there are also some medical devices that automatically measure heart rate. Measuring heart rate quickly and consistently may play important role in the early detection of heart attack and various heart rate related disorders. In this work, a mobile based system that performs quick and practical heart rate measurement. Processing RGB color changes in the image frames recorded from finger or face, which canno ...Daha fazlası

Real-Time Resistor Color Code Recognition using Image Processing in Mobile Devices

DEMİR, Muhammed Fatih | ÇANKIRLI, Ayşenur | KARABATAK, Begüm | YAVARIABDI, Amir | MENDİ, Engin | KUSETOĞULLARI, Hüseyin

This paper proposes a real-time video analysis algorithm to read the resistance value of a resistor using a color recognition technique. To achieve this, firstly, a nonlinear filtering is applied to input video frame to smooth intensity variations and remove impulse noises. After that, a photometric invariants technique is employed to transfer the video frame from RGB color space to Hue-Saturation-Value (HSV) color space, which decreases sensitivity of the proposed method to illumination changes. Next, a region of interest is defined to automatically detect resistor's colors and then an Euclid ...Daha fazlası
