Paper Abstract

Machine learning methods are being widely used in medicine to aid cancer diagnosis and detection. In the area of digital pathology, prediction heat maps produced by convolutional neural networks (CNN) have already exceeded the performance of a trained pathologist with no time constraints. To train deep learning networks, large datasets of accurately labeled ground truth data are required; however, whole slide images are often on the scale of 10+ gigapixels when digitized at 40X magnification, contain multiple magnification levels, and have unstandardized formats. Due to these characteristics, traditional techniques for the production of training and validation data cannot be used, resulting in the limited availability of annotated datasets. This research presents a Python module and method to rapidly produce accurately annotated image patches from whole slide images. This module is built on OpenCV, an open source computer vision library, OpenSlide, an open source library for reading virtual slide images, and NumPy, a library for scientific computing with Python. These Python scripts successfully produce 'ground truth' image patches and will help transfer advances in research laboratories into clinical application by addressing many of the challenges associated with the development of annotated datasets for machine learning in histopathology.
