Fig. 4From: A deformable template method for describing and averaging the anatomical variation of the human nasal cavityDeformable registration. a Two example cross-sections of half of the nasal cavity. b The cross-sections are superimposed and aligned. c.1 A close-up of the rectangular region in (b). c.2 Taking the median image results in a mask that conforms poorly with the input shapes. c.3 With deformable alignment, we can obtain a better superposition, and c.4 a mask that preserves input shapes to a larger degreeBack to article page
