METHOD AND SYSTEM FOR ASSESSING QUALITY OF COMMODITIES
First Claim
1. A method of assessing quality of commodities, the method comprising:
- receiving, by a processor of a quality assessment system, an input image of commodities captured by at least one image sensor coupled with the processor;
segmenting, by the processor, the input image to generate a plurality of segmented images of the input image;
determining, by the processor, a feature score for each of a plurality of generalized features identified based on random combination of pixels in each segmented image, wherein the plurality of generalized features is generated during training of labelled commodity images;
computing, by the processor, a regression score of each of the plurality of segmented images based on the feature score and a predetermined weightage score corresponding to the plurality of generalized features, wherein the weightage score is dynamically determined during training of labelled commodity images;
determining, by the processor, a likelihood score for each segmented image with respect to each of one of more predefined categories of commodities by comparing the regression score with predetermined regression score of each of the one or more predefined categories of commodities, wherein the predetermined regression score is determined during training of labelled commodity images; and
classifying, by the processor, each of the plurality of segmented images to one of the one or more predefined categories of commodities based on the likelihood score for assessing quality of the commodities.

Abstract
The present disclosure relates to method and system for assessing quality of commodities. An image of bulk commodity is captured and segmented into one or more segmented images for classification into one of predefined categories of commodities. The method and system classify the commodities based on generalized features created from training images. One or more features in the training images are determined and grouped to obtain the generalized features. A feature score and corresponding weightage score of the generalized feature is then determined to estimate a predetermined regression score. Based on the generalized features and predetermined regression score, a likelihood score of the segmented image is determined that enables the classification of the input image to one of the predefined categories of commodities. Thus, the present disclosure enables quality assessment of commodity by categorizing each commodity of input image into corresponding category with improved accuracy and reduced classification error.
