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 ... -
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 ... -
Moving object detection using adaptive subband decomposition and fractional lower-order statistics in video sequences
Bagci, A. M.; Yardimci, Y.; Çetin, A. Enis (Elsevier, 2002)In this paper, a moving object detection method in video sequences is described. In the first step, the camera motion is eliminated using motion compensation. An adaptive subband decomposition structure is then used to ... -
QR-RLS algorithm for error diffusion of color images
Unal, G. B.; Yardimci, Y.; Arıkan, Orhan; Çetin, A. Enis (SPIE, 2000)Printing color images on color printers and displaying them on computer monitors requires a significant reduction of physically distinct colors, which causes degradation in image quality. An efficient method to improve the ... -
Wheat and hazelnut inspection with impact acoustics time-frequency patterns
İnce, N. F.; Onaran, İbrahim; Tewfik, A. H.; Kalkan, H.; Pearson, T.; Çetin, A. Enis; Yardimci, Y. (ASABE, 2007-06)Kernel damage caused by insects and fungi is one of the most common reason for poor flour quality. Cracked hazelnut shells are prone to infection by cancer producing mold. We propose a new adaptive time-frequency classification ...
