Abstract

In recent years, computational pathology is rapidly developing. This resulted in various artificial intelligence approaches that have been proposed and applied to images common to the pathology practice, i.e. Whole Slide Images. It is very important to pre-process these images for a deep learning classifier because they are simply too large to feed into such a network. In order to get useful information from these images, we propose a new background removal method for the extracted Regions Of Interest in these images. We combine traditional morphology image operators and a U-Net framework. Firstly, we pre-process the images by using Contrast Limited Adaptive Histogram Equalization and thresholding. Then we predict the mask by using pre-trained U-Net weights. Finally, we use morphological opening and propagation operators on the predicted mask to refine the masks. The experiments based on different types of staining (H&E, PAS, and JONES silver) show the effectiveness of our method compared to 3 state-of-the-art models.
