Johne’s disease is one of the most widespread bacterial diseases of domestic animals. It induces emaciation, decrease in milk and meat production, diarrhea and death. It causes yearly losses which exceed $1.5 billion in the United States, and its impact on the world economy is enormous. In this thesis an automatic intelligent computer-aided system is proposed for diagnosis of Johne's disease, the system uses image analysis and computer vision techniques to extract features from two different microscopic images and irrelevant features are eliminated. Neural Networks and k-nearest neighbor are used as a classification technique for the extracted features to diagnose the Johne's disease.
The proposed system performs two tests; histopathological examination and the acid fast stain test. Histopathological examination depends on extracting 192 different texture features and then the features are minimized into only 8 features and classified using Artificial Neural Networks.
