Abstract
A set of enhancements to further improve the performance of deep learning artificial intelligence algorithms trained to detect and localize colon polyps. The enhancements spanning training data mining efficiencies and automation, training data augmentation, early detection of polyps enable a more performant colon polyp detection solution for use on colonoscopy procedure recordings or live procedures in endoscopy centers.
Claims11
A method of enhancing training of a colon polyp detector using a deep learning-based object detector, comprising:
- gathering a polyp early appearance image training dataset that includes a plurality of video clips each including an initial image of a polyp that is just starting to appear in frame;
- sampling the plurality of video clips in the initial portion including the initial image of the polyp at a first sampling rate to generate polyp early appearance image training data;
- sampling a remainder portion of the plurality of video clips at a second sampling rate, the second sampling rate being slower than the first sampling rate, to generate polyp image training data;
- and
- training the colon polyp detector with both the polyp early appearance image training data and with the polyp image training data.
