Classification of closed and open shell pistachio nuts using principal component analysis of impact acoustics
Çetin, A. Enis; Pearson, T. C.; Tewfik, A. H. (IEEE, 2004-05)An algorithm was developed to separate pistachio nuts with closed-shells from those with open-shells. It was observed that upon impact on a steel plate, nuts with closed-shells emit different sounds than nuts with open-shells. ... -
Classification of closed-and open-shell pistachio nuts using voice-recognition technology
Çetin, A. Enis; Pearson, T. C.; Tewfik, A. H. (American Society of Agricultural and Biological Engineers, 2004)An algorithm using speech recognition technology was developed to distinguish pistachio nuts with closed shells from those with open shells. It was observed that upon impact with a steel plate, nuts with closed shells emit ... -
Detection of empty hazelnuts from fully developed nuts by impact acoustics
Onaran, İbrahim; Dülek, Berkan; Pearson, T. C.; Yardımcı, Y.; Çetin, A. Enis (IEEE, 2005)Shell-kernel weight ratio is the main determinate of quality and price of hazelnuts. Empty hazelnuts and nuts containing undeveloped kernels may also contain mycotoxin producing molds, which can cause cancer. A prototype ... -
Detection of fungal damaged popcorn using image property covariance features
Yorulmaz, O.; Pearson, T. C.; Çetin, A. (Elsevier, 2012)Covariance-matrix-based features were applied to the detection of popcorn infected by a fungus that causes a symptom called " blue-eye" . This infection of popcorn kernels causes economic losses due to the kernels' poor ... -
Detection of insect damaged wheat kernels by impact acoustics
Pearson, T. C.; Çetin, A. Enis; Tewfik, A. H. (IEEE, 2005-03)Insect damaged wheat kernels (IDK) are characterized by a small hole bored into the kernel by insect larvae. This damage decreases flour quality as insect proteins interfere with the bread-making biochemistry and insect ... -
Detection of underdeveloped hazelnuts from fully developed nuts by impact acoustics
Onaran, I.; Pearson, T. C.; Yardimci, Y.; Çetin, A. Enis (American Society of Agricultural and Biological Engineers, 2006)Shell-to-kernel weight ratio is a vital measurement of quality in hazelnuts as it helps to identify nuts that have underdeveloped kernels. Nuts containing underdeveloped kernels may contain mycotoxin-producing molds, which ... -
Discrimination between closed-and open-shell (Turkish) pistachio nuts using undecimated wavelet packet transform
Ince, N. F.; Goksu, F.; Tewfik, A. H.; Onaran, I.; Çetin, A. Enis; Pearson, T. C. (American Society of Agricultural and Biological Engineers, 2008)Due to low consumer acceptance and the possibility of immature kernels, closed-shell pistachio nuts should be separated from open-shell nuts before reaching the consumer. A system using impact acoustics as a means of ... -
System for removing shell pieces hazelnut kernels using impact vibration analysis
Çetin, A. Enis; Pearson, T. C.; Sevimli, R. A. (Elsevier BV, 2014-02)A system for removing shell pieces from hazelnut kernels using impact vibration analysis was developed in which nuts are dropped onto a steel plate and the vibration signals are captured and analyzed. The mel-cepstral ...
