Rohan Subramaniam developed robust image analysis and classification pipelines for the arvindkrishna87/STAT390_SP25_CMIL repository, focusing on histology data. He designed and implemented end-to-end workflows for data preprocessing, patch extraction, and model training using Python and deep learning frameworks such as TensorFlow and PyTorch. His work included dynamic SSIM-guided averaging for multi-stain image patches, improving reliability in the presence of misalignments, and prototyping CNN and AlexNet-based classifiers with reproducible evaluation metrics. Rohan’s contributions emphasized modularity, reproducibility, and scalability, resulting in automated, production-ready pipelines that support cross-stain analysis and reduce manual intervention in pathology image processing tasks.

Jun 1, 2025June 2025 performance summary for arvindkrishna87/STAT390_SP25_CMIL: Delivered SSIM-guided dynamic averaging for multi-stain image patches. Introduced a dynamic averaging strategy that uses SSIM to decide whether Sox10 stained images should be included in the averaging with H&E and Melan. If SSIM is below threshold, only H&E and Melan are averaged; if SSIM meets threshold, all three (H&E, Melan, Sox10) are averaged. This enhances robustness of image analysis by handling misalignments in stain imaging and improves the reliability of downstream metrics. This work supports more automated, scalable pathology analysis with reduced need for manual corrections. Commits: 5df74d19189167c244baceee302b8afa2c09c024 (dynamic averaging to incorporate two-stain matches).
