• Title: Color Deconvolution applied to Domain Adaptation in HER2 histopathological images
• Authors: David Anglada-Rotger, Ferran Marqu\'es, Montse Pard\`as
• Abstract summary: We propose a new approach for facing the color normalization problem in HER2-stained images of breast cancer tissue. We combine the Color Deconvolution technique with the Pix2Pix GAN network to present a novel approach to correct the color variations between different HER2 stain brands. Our approach focuses on maintaining the HER2 score of the cells in the transformed images, which is crucial for the HER2 analysis.

• Abstract: Breast cancer early detection is crucial for improving patient outcomes. The Institut Catal\`a de la Salut (ICS) has launched the DigiPatICS project to develop and implement artificial intelligence algorithms to assist with the diagnosis of cancer. In this paper, we propose a new approach for facing the color normalization problem in HER2-stained histopathological images of breast cancer tissue, posed as an style transfer problem. We combine the Color Deconvolution technique with the Pix2Pix GAN network to present a novel approach to correct the color variations between different HER2 stain brands. Our approach focuses on maintaining the HER2 score of the cells in the transformed images, which is crucial for the HER2 analysis. Results demonstrate that our final model outperforms the state-of-the-art image style transfer methods in maintaining the cell classes in the transformed images and is as effective as them in generating realistic images.

  Image-to-image translation (I2I) methods allow the generation of artificial images that share the content of the original image but have a different style. I2I methods were also employed in histopathology for generating artificial images of in silico stained tissues from a different type of staining. We compare twelve stain transfer approaches, three of which are based on traditional and nine on GAN-based image processing methods.
