Oil palm bunch ripeness classification using fluorescence technique

Palm oil fresh fruit bunch ripeness grading identification using color features

“…Elais guineensis of nigrescens (African palm oil) is the typical species found in Malaysia [2][3]. It can only be harvested after three to four years of planting and it can reach up to 30 feet high.…”

Fluorescence indices for monitoring the ripening of tomatoes in pre- and postharvest phases

“…With in tomatoes (Farneti et al, 2012;Seifert et al, 2014), and chlorophyll content in apples (Zude-Sasse et al, 2002;Kuckenberg, 2008) and bananas (Zude-Sasse, 2003) as well as carotenoid content in carrots (Zude-Sasse et al, 2007). Another method, fluorescence spectroscopy, has been proposed for the analysis of tomato ripening in the laboratory (Lai et al, 2007), whereas a hand-held multiparametric sensor has been used to characterize ripening and quality attributes of apples (Betemps et al, 2012), grapes (Cerovic et al, 2009;Ben Ghozlen et al, 2010;Agati et al, 2013) and oil palm bunches (Hazir et al, 2012a(Hazir et al, , 2012b). This portable system provides robust data on the pigment composition of leaves and fruits (Cerovic et al, 2002(Cerovic et al, , 2009Betemps et al, 2012;Müller et al, 2013) through the excitation of chlorophyll fluorescence with different wavelengths.…”

Classification and regression tree theory application for assessment of building damage caused by surface deformation

“…The analyses prove that when the missing data do not exceed 5 % of the set, satisfactory results of CART classification can be expected (Yong 2006). Thanks to its transparence and high accuracy, the method is used in various branches of science, e.g., medicine (Ture et al 2009), photogrammetry (Yang et al 2003), economics (Chang 2011), environmental protection (Smeti et al 2009), food science (Hazir et al 2012) and chemistry (Chudzinska and Baralkiewicz 2011). The CART classification is made in a few stages.…”
