Image analysis for smart machine of nutmeg sorting

Abstract

Nutmeg is an Indonesian agricultural commodity that has been recognized and interested by the world import market. In the last decade, several cases of export of nutmeg from Indonesia have been rejected due to post-harvest handling contaminated with Aflatoxin. One of the causes is the process of sorting and guaranteeing the quality of products that are done traditionally and not yet perfect. This paper presented the prototype development of image acquisition station using two cameras to capture nutmeg surface in smart sorting machine. In addition, the ultraviolet light was added to ease the detection of aflatoxin using colour segmentation method. Moreover, based on SNI 01-0006-1993 and SNI 01-0007-1993, there are some criteria to categorize the quality of nutmeg such as shape, texture and colour. The experimental study of image analysis showed that our proposed sorting system could classify nutmeg based on SNI and calculate contamination area of aflatoxin.
