in addition the digital image analysis step which consists of deriving the RGB values
from pixels of a digital image could be achieved in several methods. Hence. an author
encourages the use of the more recognized Matlab or Image] programs in comparison
with Photoshop program to study their effects on the average color difference. The
books on digital image processing using Matlab by Gonzalez ct al. (2004) and
introduction lo digital image processing with Matluh by McAndrcw (2004) can be
found very useful for the image analysis. Perhaps. creating the simple software for color
analysis and conversion leading to the automatic application will be a plus.
pineapple images can be improved by increasing the data.
