Machine Vision Applications to Locate Fruits, Detect Defects and Remove Noise: a Review

Every year tons of fruits are processed in agro and food processing industry. The quality of the fruit plays a vital and is determined by shape, color and size. Manual sorting is one method to sort the fruits that is tedious and takes more time to process. To avoid the above difficulties, automatic sorting and grading can be done using machine vision system. Machine vision methods provide automatic inspection and analysis based on images. Images used for machine vision can be hyper spectral and multi spectral images. The images taken from the camera is affected by some sources of noise. This paper reviews the various techniques used in automatic inspection of fruits using machine vision techniques for defects identification in different fruits and also reviews about the removal of noises.
