Abstract

This paper presents a freshness classification model for determining the quality of amla (Phyllanthus emblica) using features extracted from the progressively deteriorating shapes. Estimation of the peripheral distance from the centroid is carried out to develop key features regarding the shape of the samples, followed by developing two classifier models using support vector machine (SVM) and artificial neural network (ANN) to segment the samples into Good and Deteriorated classes. The proposed algorithm is simple in analysis as it includes geometry-based computation for identifying the surface irregularities and shape changes occurring due to aging the samples. Canny edge detection model is used to obtain the peripheral edges, followed by analyzing the same using “ConvexImage.” High accuracy of classification, exceeding 90%, is achieved in most cases, using three different feature parameters so developed, either as univariate or multivariate schemes of analysis. Besides, the sample images are captured using smartphones only. Thus, high accuracy of freshness classification, along with ease of analysis and image capturing using the phone camera itself, makes the algorithm suitable for implementing in low memory devices such as smartphones, which would also make the proposed model more widely exploring.
