Abstract
Colorectal cancer (CRC) is one of the leading causes of death worldwide. Fortunately, its early detection and treatment highly improves the survival rates and reduces costs. In this regard, screening programs and colonoscopy play an essential role. Artificial intelligence (AI) and deep learning (DL) have arisen with great success and been widely applied to medical imaging for the last few years and efforts have also been placed to develop methods to improve the adenoma detection rate in colonoscopy. In this chapter, polyp detection, localization, segmentation, and classification using colonoscopy are addressed. Works on these tasks have shown an exponential growth in the last few years. In the first place, the elements required for applying supervised DL methods for colorectal polyps in colonoscopy are introduced. The focus is placed on the model architecture, the dataset, the loss function, data augmentation, and metrics. Next, the currently openly available datasets that might be useful for future research are presented, before discussing methods for polyp detection, localization, segmentation, and classification. Lastly, some challenges and future trends in these fields are commented. This chapter about AI and DL for colorectal polyps in colonoscopy put forward the wide range of applications and research lines that can be further investigated with promising results as shown by the already currently published works, and always with the ultimate goal of assisting the endoscopist to improve CRC detection and diagnosis, which would eventually lead to better patient outcomes.
