Noise Removal Methods of Chili Pepper Images for Detecting Toxin Using Neural Networks

Professor Department of Computer Science, Avinashilingam Deemed University, Coimbatore -43. Tamilnadu, India. Abstract: Mycotoxins are toxic substances produced mostly as secondary metabolites by fungi that grow on seeds and feed in the field, or in storage. The food-borne Mycotoxins likely to be of greatest significance for human health are Aflatoxin and Fumonisins. Chili pepper is also affected by Aflatoxin contamination during harvesting, production and storage periods. X-ray is a very popular non-destructive testing method. In this proposed work, X-ray images of chilli pepper samples were collected and processed using image processing methods. This research paper gives a review of existing approaches of pre-processing methods compared with the proposed 4-connected median filter. Based on the performance measure analysis the best pre-processing method is selected, to remove the noise presence in chili pepper X-ray images.
