Abstract: System, method, and computer program product to perform an operation, comprising sampling a plurality of points and a plurality of segments of a curve on a surface of a three-dimensional model, storing each sampled point as a respective vertex of a plurality of vertices and each sampled segment as a respective half-edge in a curve network of the model surface, upon determining that a first half-edge and a second half-edge connect two of the plurality of vertices, generating a first halfchain connecting the first half-edge and the second half-edge, wherein each connected vertex comprises either a corner or an open endpoint, and upon determining that three consecutive halfchains form a loop comprising at least three corners, generating a first patch for a space enclosed by the loop, wherein the first patch is represented as a quad mesh with a respective set of vertices, faces, and half-edges.

Abstract: The disclosure provides an approach for transferring image edits from a source image to target images. In one embodiment, a warp application receives a user-selected region of interest in a source image and determines for the region of interest content-aware bounded weight functions and seed locations for the same. For each of the target images, the warping application initializes a linear blend skinning subspace warp to a projection onto a feature space of a piecewise affine map from scale invariant feature transform features of the source image to the target image. After initializing the warps, the warping application iteratively optimizes the warps by applying the inverse compositional Lucas-Kanade procedure and using the content-aware weight functions in said procedure. Edits made to the source image may automatically be transferred to target images by warping those edits via the optimized warp function for the respective target images.
