Very large Whole Slide Images and deep learning Whole Slide Images (WSI) typically occupy gigabytes and are too large to train models directly. That is why a preprocessing pipeline is used to work efficiently: metadata extraction, patch sampling and filtering, and generation of compact embeddings using pre-trained models such as KimiaNet. This approach drastically reduces the required storage and prepares data ready for accelerated GPU training, facilitating advanced tasks such as genetic mutation detection.
Step 1 Metadata extraction The first step consists of reading and cataloging vital information from each WSI without loading the entire image into memory. Metadata such as resolution, zoom levels, and regions of interest allow mapping the image and deciding where to extract relevant patches. This stage optimizes times and avoids processing non-useful regions.
Step 2 Patch sampling and filtering Instead of processing every pixel of the WSI, patches of manageable size are extracted. Quality filters are applied to remove areas with little tissue or artifacts, and content heuristics and fast models are used to select only informative patches. This significantly reduces the number of samples and the cost of storage and computation.
Step 3 Embedding generation with KimiaNet To compact visual information, embeddings are calculated with pre-trained networks such as KimiaNet. Embeddings are low-dimensional vectors that capture relevant features of the patch and occupy much less space than the original images. These vectors are ideal for training classification or mutation detection models using GPU, enabling fast and scalable iterations.
Operational benefits The pipeline combining metadata, filtering, and embeddings offers several concrete benefits: drastic reduction of the storage required for WSI datasets, faster and more efficient GPU training, the possibility of reusing embeddings for multiple experiments, and compatibility with cloud infrastructures for production deployments.
Applications in biomedicine This workflow is applied in genetic mutation detection, tumor subtyping, predictive biomarkers, and research projects that require scaling from clinical samples to massive cohorts without multiplying storage costs and computation time.
