EndoWave: 4D Gaussian Splatting with Rational Wavelet for Endoscopic Reconstruction
EndoWave is a 4D Gaussian Splatting method designed for high-fidelity reconstruction of dynamic endoscopic videos. It improves upon existing methods by unifying spatio-temporal Gaussians, using optical flow for geometric constraints, and incorporating multi-resolution rational wavelets to handle tissue motion and frequency details effectively.
