Automatic Detection and Classification of Non Metallic Inclusions in Steel via Image Processing
Aydilek, Huseyin; Polat, Ediz (Ieee, 2014)Non-metallic chemical components (silicate, sulfide, alumina, globular oxide) originated from production process cause inclusions in steel. These inclusions are one of the important factors that directly affect quality of ... -
A color image segmentation approach for content-based image retrieval
Özden, Mustafa; Polat, Ediz (Pergamon-Elsevier Science Ltd, 2007)This paper describes a new color image segmentation method based on low-level features including color, texture and spatial information. The mean-shift algorithm with color and spatial information in color image segmentation ... -
The Effect of Dictionary Learning Algorithms on Super-resolution Hyperspectral Reconstruction
Simsek, Murat; Polat, Ediz (Ieee, 2015)The spatial resolutions of hyperspectral images are generally lower due to imaging hardware limitations. Super-resolution algorithms can be applied to obtain higher resolutions. Many algorithms exist to achieve super-resolution ... -
Feature Selection for Multi-SVM Classifiers in Facial Expression Classification
Gunes, Turan; Polat, Ediz (Ieee, 2008)Facial expressions are non-verbal signs that play an important role between interpersonal communications and also they are the most effective way to describe human emotions. The correct and fast extraction/recognition of ... -
Feature selection in facial expression analysis and its effect on multi-SVM classifiers
Gunes, Turan; Polat, Ediz (Gazi Univ, Fac Engineering Architecture, 2009)Facial expressions are non-verbal signs that play important role to provide complete meaning in human communication. While humans can easily comprehend the facial expressions, it is not valid for the computers, thus the ... -
A nonparametric adaptive tracking algorithm based on multiple feature distributions
Polat, Ediz; Özden, Mustafa (Ieee-Inst Electrical Electronics Engineers Inc, 2006)This paper presents an object tracking framework based on the mean-shift algorithm, which is a nonparametric technique that uses statistical color distribution of objects. Tracking objects through highly similar-colored ... -
Sparse Representation-based Dictionary Learning Methods for Hyperspectral Super-Resolution
Simsek, Murat; Polat, Ediz (Ieee, 2016)Due to hardware limitations, hyperspectral imagery has low spatial resolution. It can be obtained super-resolution hyperspectral imagery by means of sparse representation-based methods that are designed for improving spatial ... -
A video-based eye pupil detection system for diagnosing bipolar disorder
Akinci, Gokay; Polat, Ediz; Kocak, Orhan Murat (Tubitak Scientific & Technical Research Council Turkey, 2013)Eye pupil detection systems have become increasingly popular in image processing and computer vision applications in medical systems. In this study, a video-based eye pupil detection system is developed for diagnosing ... -
Yüz ifade analizinde öznitelik seçimi ve çoklu SVM sınıflandırıcılarına etkisi
Güneş, Turan; Polat, Ediz (2009)Yüz ifadeleri, insan ilişkilerinde anlam bütünlüğünün sağlanması için büyük rol oynayan, sözlü olmayan işaretlerdir. İnsanoğlu yüz ifadelerini kavramada herhangi bir zorluk çekmezken, bu durum makineler için geçerli olmayıp, ...
