agricultural and food science. B. Image Acquisition

III. PROPOSED METHOD There are many methods of processing signals from the
camera to access the properties of objects. Image processing
process includes the image acquisition using the fixed camera
placed above the conveyor which captures images with short
scanning cycle. To increase the quality of images, the high
resolution camera was equipped to collect the images (Cannon
- EOS 600D-18 MP), position of the camera is very important,
set the camera in the image acquisition chamber so that the
field of view of the camera is wide enough and not impede the
actuators during operation.
C. Pre-Processing of Images
The images obtained during image acquisition is not directly
suitable for the process of identification of fruits because of
its poor resolution and unwanted background, noise, weather
conditions, The sorting and grading performance of the
system depends on the quality of the images captured by
camera, since various measures/features calculated from the
images of the mangoes will be used for sorting and grading.
The mechanism for the image capturing is shown in Figure 2

Based on accuracy this proposed algorithm classified the


mangoes into various grades .Focusing on the texture on the
surface of the mango can also be used as a feature parameter
for grading so that the overall accuracy can be improved.
