A computer vision system developed by the Institute of Agricultural Engineering, Potsdam,
Germany with CCD camera JVC KY-F50E (zoom lens F2.5 and focal lengths of 18-108 mm)
was used to capture the images of bananas. The size of the captured image was 720x576 pixels
by 24 bits. The bananas were illuminated using four fluorescent lamps arranged as front lighting
at a height of 35cm above the samples in the form of a square for uniform effect. The angle
between the camera lens axis and the lamps was 45° since diffused reflections responsible for
colour occurred at 45° from the incident light. Óption as grabber board (Bio scan Inc., USA)
software was used to acquire the images directly on the computer display and store them in
the computer in bmp format.
