Detail Preserving Shape Deformation in Image Editing
Abstract
Shape deformation is a common practice in digital image editing, but can unrealistically stretch or compress texture detail. We propose an image editing system that decouples feature position from pixel color generation, by resynthesizing texture from the source image to preserve its detail and orientation around a new feature curve location. We introduce a new distortion to patch-based texture synthesis that aligns texture features with image features. A dense correspondence field between source and target images generated by the control curves then guides texture synthesis.

***** A matte is manually selected on the ears to exclude the
background from synthesis. Some artifacts along the silhouette
are actually caused by the matte. *****
(The following fat bunny has a different set of control lines, as shown in the corner.)
