Classification of Hazelnut Kernels by Using Impact Acoustic Time-Frequency Patterns
Kalkan, Habil; Ince, Nuri Firat; Tewfik, Ahmed H.; Yardimci, Yasemin; Pearson, Tom (Springer Science and Business Media LLC, 2007-11-11)
Hazelnuts with damaged or cracked shells are more prone to infection with aflatoxin producing molds ( Aspergillus flavus). These molds can cause cancer. In this study, we introduce a new approach that separates damaged/cracked hazelnut kernels from good ones by using time-frequency features obtained from impact acoustic signals. The proposed technique requires no prior knowledge of the relevant time and frequency locations. In an offline step, the algorithm adaptively segments impact signals from a training...
Classifications of hardgrounds based upon their strength properties
Doğan, Abdullah; DOGAN, M; Karpuz, Celal (2006-06-01)
Rock samples from the Baglum-Kosrelik area, 30 km north of Ankara, Turkey have been studied petrographically in detail to differentiate between nodular limestones and hardgrounds. However, it is found that petrographic criteria alone may not always be used to differentiate between nodular limestones and true hardgrounds. Distinction between hardgrounds and other well indurated carbonate rocks can be made based upon the strength properties of the rocks, including uniaxial compressive strengths, triaxial comp...
Classification of hyperspectral images based on weighted DMPs
Ulusoy, İlkay; MURA, Mauro Dalla (2012-07-27)
This paper presents a classification method for hyperspectral images utilizing Differential Morphological Profiles (DMPs) which permit to include in the analysis spatial information since they can provide an estimate of the size and contrast characteristics of the structures in an image. Due to the wide variety of objects present in a scene, the pixels belonging to the same semantic structure may not have homogeneous spatial and spectral features. In addition, instead of a single peak (which can be related ...

Classification of migraineurs using functional near infrared spectroscopy data
Sayıta, Yusuf; Temizel, Alptekin; Akın, Ata; Department of Medical Informatics (2012)
Classification of migraineur and healthy subjects using statistical pattern classifiers on functional Near Infrared Spectroscopy (NIRS) data is the main purpose of this study. Also a statistical comparison between trials that have different type of classifiers, classifier settings and feature sets is done. Features are extracted from raw light measurement data acquired with NIRS device, namely Niroxcope, during two separate previous studies, using Modified Beer-Lambert Law. After feature extraction, Naïve B...
