Abstract:
Abstract: Objective To establish a semantic segmentation model for colorectal polyps in endoscopic images based on DeepLab V3+. Methods A total of 1 500 endoscopic images of colorectal polyps were collected, including 1 000 from Hyper-Kvasir public dataset and 500 from the First Affiliated Hospital of Soochow University, and randomly divided into training set (n=1 200) and validation set (n=300). Meanwhile, the images from Jintan Affiliated Hospital of Jiangsu University were collected as test set (n=220). After the endoscopic image segmentation and labeling, the images and masks were loaded into a deep learning neural network with DeepLab V3+ as the architecture for training, thereby developing a semantic segmentation model. Results The accuracy, mean intersection over union, and Dice coefficient of the developed model were 97.2%, 85.8% and 0.924 in the internal validation set, and 98.0%, 80.1% and 0.890 in the external test set. Conclusion The DeepLab V3+ based semantic segmentation model for colorectal polyps in endoscopic images exhibits excellent performances, and it can serve as an effective method for the detection and diagnosis of colorectal polyps.
