  • OPTIMISED DEEP LEARNING FOR ORAL CANCER CLASSIFICATION
    Chellasamy Sulochana, Mahadevan Sumathi
    Acta Polytechnica, 2026
    Oral cancer detection is essential, especially in areas with high occurrence rates, is essential for better early diagnosis and individualised treatment plans. SV-OnionNet is a deep learning framework presented in this article that aims to improve the classification accuracy of oral cancer diagnosis. While maintaining important structural details, the method lowers noise in medical pictures by integrating an adaptive Non-Linear Means (NLM) filter. Spatial features are improved by the Label-Guided Attention (LGA) module, which guarantees constant labelling and improves feature extraction. By enabling accurate pixel-level segmentation of lesions, Seg-UNet provides increased classification reliability. The Support Vector Machines (SVM) deep learning classification model used in the SV-OnionNet architecture preserves spatial relationships for improved feature learning, replacing traditional fully linked layers (LKN). The Competitive Search Optimization (CSO) algorithm fine-tunes model parameters, therefore optimising feature selection and classification. The evaluation on the Mouth and Oral Diseases dataset demonstrated exceptional accuracy, precision, recall, and specificity, with the proposed classification achieving a 99.94% accuracy. These findings emphasise the effectiveness of SV-OnionNet in improving the diagnostic accuracy and reliability. The study highlights the potential of integrating deep learning techniques with optimisation strategies to advance oral cancer detection. Future research will focus on expanding datasets and exploring additional optimisation methods to further improve the classification performance.

  • Impact of Microorganisms on Food Spoilage and Human Health: A Comprehensive Review of Advances in Identification using Image Processing and Artificial Intelligence Techniques
    Mahalakshmi Priya R, Sumathi M
    International Research Journal of Multidisciplinary Scope, 2025
    Food spoilage and human health are greatly affected by microorganisms, such as bacteria, algae, fungi, and protozoa. While traditional identification methods are reliable, they are often laborious and time-consuming. In recent years, artificial intelligence (AI) and image processing have made significant progress in identifying and classifying microorganisms quickly and accurately. In this review, we will examine image processing and artificial intelligencebased techniques for identifying and classifying microorganisms relevant to human health and food spoilage, comparing their effectiveness to traditional methods and assessing their impact on food safety. Bacteria, algae, fungi, and protozoa are the four major groups of microorganisms examined in this review. A review of applications in food safety, clinical microbiology, and environmental monitoring is presented in this paper. It examines how bacteria, yeast, and molds cause food spoilage and examines their mechanisms of action. Furthermore, the article highlights common foodborne illnesses and the health consequences of eating contaminated food. The paper also discusses advances in identifying spoilage-causing microorganisms, with a particular emphasis on artificial intelligence (AI) and image processing. With modern techniques, microbial contamination can be detected more accurately and efficiently, thus improving food safety. Finally, the review concludes by analyzing current challenges and future directions in the field, emphasizing the need for continued innovation in microbial detection methods. In the review, rapid detection of foodborne pathogens is highlighted, as well as automated spoilage monitoring. This technology has the potential to revolutionize food safety practices and clinical microbiology, so it must continue to be developed and validated.

  • Bridging AI and Ecology: CILNN and XAI for Acoustic Based Prediction of Dangerous Wild Animals
    Govindaprabhu GB, Sumathi M, Sharan Neyvasagam, Naveen Ananda Kumar J
    International Research Journal of Multidisciplinary Scope, 2025
    In habitats that are encroaching on humans, human-wildlife conflict is an increasing global challenge. There is a significant risk of human injury and retaliatory action being taken if humans encounter dangerous animals. This work presents a novel approach to automated detection and classification of dangerous animals using audio signals, with a focus on model interpretability. This work introduces the Convolutional Interconnected Layer Neural Network (CILNN), a deep learning architecture designed to effectively process and classify animal vocalizations. Our method leverages a comprehensive set of audio features, including Mel-frequency cepstral coefficients (MFCCs) and spectral characteristics, optimized through SHAP-based feature selection. The CILNN incorporates interconnected layers and attention mechanisms to enhance feature extraction and model performance. It evaluates proposed approach on a diverse dataset of vocalizations from five dangerous animal species: bears, bison, cheetahs, elephants, and wild boars. Experimental results demonstrate that the CILNN outperforms traditional machine learning models such as Random Forests and Decision Trees in classification accuracy and robustness. Crucially, it employs Explainable AI (XAI) techniques, including SHAP values and decision tree visualizations, to interpret the decision-making processes of both our CILNN (90.6% accuracy) and other models. This interpretability analysis provides insights into feature importance and model behavior, enhancing trust and understanding in the classification process. Our work contributes to wildlife monitoring and human-wildlife conflict mitigation by offering an efficient, accurate, and interpretable method for acoustic-based animal detection

  • Safeguarding Humans from Attacks Using AI-Enabled (DQN) Wild Animal Identification System
    Govindaprabhu GB, Sumathi M
    International Research Journal of Multidisciplinary Scope, 2024
    Without advanced artificial intelligence (AI) technologies, monitoring and identifying wildlife has become increasingly difficult. To examine AI-driven methodologies for wild animal identification, this work uses a diverse dataset of annotated images with human, domestic and wild animal annotations. Convolutional Neural Networks (CNNs), AlexNet, and Deep Q-Learning (DQN) models are developed and compared by combining sophisticated preprocessing techniques such as dynamic color space conversion and day-night image translation. The models are evaluated on accuracy, precision, recall, F1-score, and mean percent error (MPE) loss metrics for classifying diverse species. The DQN model achieves the best performance with 79.5% accuracy, 0.78 precision, 0.84 F1-score, and 0.24 MPE loss. These findings demonstrate AI's potential to support conservation efforts by enabling accurate and automated wildlife monitoring. The comparative assessment of different models and factors influencing performance provides methodological insights to guide future research toward robust and generalizable AI solutions for biodiversity and habitat management.
  • Enhancing Oral Cancer Diagnosis: IAWMF based Preprocessing in RGB and CT Images
    C. Sulochana, M. Sumathi
    2024 International Conference on Recent Advances in Electrical Electronics Ubiquitous Communication and Computational Intelligence Raeeucci 2024, 2024
    Globally, there are over 350,000 cases of oral cancer, mainly oral squamous cell carcinomas that arise in the mouth and tongue tissues. For metastatic cases, the survival rate drops dramatically from 83% to only 65% if detected early. It is challenging, however, to identify oral lesions and precancerous conditions in their earliest stages when treatment can be most effective. CT scans and intraoral RGB photography are critical imaging methods for screening and diagnosing oral cancers. It is difficult to detect oral cancer accurately with these imaging techniques due to artifacts, noise, and poor lesion visibility. In current CAD methods, preprocessing pipelines for oral cavity images across RGB and CT are not robust or tailored. An automated, adaptive, and multimodal preprocessing pipeline is presented in this study to reduce this gap by facilitating early detection of oral cancer from RGB photographs and CT scans. A region-of-interest cropping technique is used to focus on diagnostically significant areas, specialized noise filters are used to reduce noise while maintaining tissue features, and adaptive histogram equalization is used to normalize contrast dynamically across images and highlight lesions. Oral cavity images in RGB and CT formats were used to evaluate the proposed techniques. As compared to original images, the results demonstrated significant improvements in image quality, noise reduction, lesion conspicuity, and feature visibility. Among the noise filters assessed, the Iterative Adaptive Weighted Median Filter (IAWMF) performed best with PSNR 33, SNR 28.2817, and RMSE 5.7088, which indicated the filter's effectiveness for high fidelity denoising. The median filter was also capable of reducing noise effectively with PSNR of 26.7701, SNR of 22.0518, and RMSE of 11.696. Image quality was the poorest when using Total Generalized Variation. A tailored preprocessing pipeline shows promise in aiding early diagnosis and treatment of oral cancer.
