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 ... -
Falling person detection using multisensor signal processing
Toreyin, B. U.; Soyer, E. B.; Onaran, I.; Cetin, E. E. (SpringerOpen, 2008)Falls are one of the most important problems for frail and elderly people living independently. Early detection of falls is vital to provide a safe and active lifestyle for elderly. Sound, passive infrared (PIR) and vibration ... -
Identification of damaged wheat kernels and cracked-shell hazelnuts with impact acoustics time-frequency patterns
Ince, N. F.; Onaran, I.; Pearson, T.; Tewfik, A. H.; Çetin, A. Enis; Kalkan, H.; Yardimci, Y. (American Society of Agricultural and Biological Engineers, 2008)A new adaptive time-frequency (t-f) analysis and classification procedure is applied to impact acoustic signals for detecting hazelnuts with cracked shells and three types of damaged wheat kernels. Kernels were dropped ... -
Image description using a multiplier-less operator
Tuna, H.; Onaran, I.; Çetin, A. Enis (IEEE, 2009-06-05)A fast algorithm for image classification based on a computationally efficient operator forming a semigroup on real numbers is developed. The new operator does not require any multiplications. The co-difference matrix based ... -
Pulse doppler radar target recognition using a two-stage SVM procedure
Eryildirim, A.; Onaran, I. (IEEE, 2010-07-07)It is possible to detect and classify moving and stationary targets using ground surveillance pulse-Doppler radars (PDRs). A two-stage support vector machine (SVM) based target classification scheme is described here. The ... -
Sparse spatial filter via a novel objective function minimization with smooth ℓ1 regularization
Onaran, I.; Ince, N. F.; Çetin, A. Enis (Elsevier, 2013-05)Common spatial pattern (CSP) method is widely used in brain machine interface (BMI) applications to extract features from the multichannel neural activity through a set of spatial projections. These spatial projections ...
