Building an image mosaic of the placenta and its network of vessels could assist surgeons to navigate in the challenging fetoscopic environment during the procedure.<h4>Methodology</h4>We propose a fetoscopic mosaicking approach by combining deep learning-based optical flow with robust estimation for filtering inconsistent motions that occurs due to floating particles and specularities. While the current state of the art for fetoscopic mosaicking relies on clearly visible vessels for registration, our approach overcomes this limitation by considering the motion of all consistent pixels within consecInternational journal of computer assisted radiology and surgeryRobust fetoscopic mosaicking from deep learned flow fields.PMC9124660EP/P012841/1NS/A000027/1203145Z/16/ZEP/P027938/1EP/R004080/1WT101957Vasconcelos FDeprest JAlabi OBano SDavid ALStoyanov DfalseRobust fetoscopic mosaicking from deep learned flow fields.<h4>Purpose</h4>Fetoscopic laser photocoagulation is a minimally invasive procedure to treat twin-to-twin transfusion syndrome during pregnancy by stopping irregular blood flow in the placenta.
