“…However, the low coherence property of broadband light makes it less ideal for remote sensing/measurement. Multi-band assessment techniques that are based on the LED sources at specific wavelengths have been suggested [11,12]. The work distance is limited (< 1m) and technically impractical for on-site operation and on-plant assessment.…”

“…Near infrared spectrometry (NIRS) is one of the nondestructive methods (Ismail, 2010), consisting of light detection and ranging (LiDAR) scanning systems that have been studied to classify oil palm ripeness in the Malaysian oil palm industry, where the proposed approach was based on calculating the reflectance percentage using the concept of linearity (Zulkifli et al, 2018). Another application classified oil palm ripening into under-ripe, ripe and over-ripe categories using hand-held, multi-parameter fluorescence sensors and blue-green (447 nm) and far-red (685 nm) wavelengths.…”

“…Classification methods such as k-Nearest Neighbor (KNN) were also used to compare feature values in each image according to the smallest differences from each study data [ 9 ]. However, due to the changes in light intensity throughout the day, images captured at different times may cause some discrepancies when determining the ripeness of oil palm fruits using the computer vision technique [ 10 ]. To overcome these problems, this study extends our previous work using Raman spectroscopy for oil palm fruit ripeness classification, due to its high potential in analyzing the biochemical content of a fruit sans light dependency [ 11 , 12 ].…”
