images directly, sharp edges at the boundary can be noticeable. By blending low-frequency components smoothly and high-frequency details selectively, the transition between images becomes natural. • The blending mask is also pyramidal, meaning it changes smoothly across scales. This ensures that low-frequency components are blended over a larger region, while high-frequency details are only blended near the boundary. NHSM - 4th year: Computer vision - pyramids (Week 2) - M.
