A diffeomorphic blender is a tool used to create smooth, seamless transitions between two different images or animations. It can be used to create special effects, or to simply make two images flow together more smoothly. The diffeomorphic blender works by warping one image to match the shape of the other image.
WebTracking and representation of shape change over time is of great interest in the field of computational anatomy. We propose a longitudinal growth model which estimates the diffeomorphic flow of a baseline image passing through a series of time-points that are the observed evolution of the template over time. We optimize the full space-time flow for …
