Thyroid tumor is an uncommon type of cancer. This cancer can be cured if it is detected promptly and treated correctly. This paper presents a tool for the detection and diagnosis of thyroid malignant areas using Co-active Adaptive Neuro-Fuzzy Inference System (CANFIS) classifier. The proposed methodology considers the image enhancement stage, feature extraction along with classification stage. The Gaussian filter is applied to enhance the thyroid image in terms of smoothening the edge regions and features are extracted from the enhanced thyroid image. These extracted features are classified using the proposed algorithm to classify the thyroid image into either benign or malignant nodule. The tumor region of interest is segmented by morphological segmentation. The performance of the planned thyroid tumor detection system is analyzed using performance parameters.
