The objective of this research was to design and implement an inexpensive computer vision system for measuring the color of a highly
heterogeneous food material not only in shape as well in color such as potato chips in L*a*b* units from RGB images. The system was
composed of (i) a digital color camera for acquiring the images in a digital format, (ii) a computer for storage the images, (c) image analysis
routines integrated into a software programmed in Matlab that converts the color RGB of the food image into L*a*b* units. In this
way the color of potato chips can be calculated in L*a*b* units over representative areas and in a reproducible way. The kinetics of color
changes in potato slices during frying at four temperatures was followed using the implemented The Kingdom of Saudi Arabia is the world’s largest date producer.
It produces almost 400 date varieties in bulk. After harvesting,
if the dates are not processed timely (within harvesting
season), it may cost dearly to the date growers. In post harvesting
operations the date grading and sorting process is the
prime source of delay. The reason is that it is a repetitive, labor
intensive and time consuming process and it is carried out by
humans manually through visual inspection. The manual processing
pose added problems of maintaining the consistency
and uniformity in date grading. Therefore, a computer mediated
system that can mimic the human grading and sorting
process may adequately expedite the process as well it may sort
