Features Based Fruit Gradation System using Image Processing

Abstract

An automatic fruit quality inspection system for sorting and grading of fruits is discussed here.The quality of fruit is an essential factor for the customer, and so it is essential for marketing a uniformly high-quality fruit. The manual inspection system for sorting is replaced in this system. The system consists ofa combination of software and hardware. Opensource software is used as it is freely available. For covering a total area of fruit, it is placed in a rotating disk. The system performance mainly depends on thresholds used for size and color. Though the value of sizeand color will vary with a different image but the developed system did not require adjustment in threshold value for grading of fruits. This system helps in speed up process, improve accuracy and efficiency. The system accuracy is about 92%. The image processing is carried out, and features such as color, size, and glare are extracted and processed for quality of fruits. Servo motor is used for movement of rotating disk.The fruit is graded in two varieties.
