Automatic landmark annotation and dense correspondence registration for 3D human facial images Jianya Guo, Xi Mei and Kun Tang* Abstract Background: Traditional anthropometric studies of human face rely on manual measurements of simple features, Here we describe a novel non-rigid Determining dense correspondence between 3D skull models is a very important but difficult task due to the complexity of the skulls. Non-rigid registration is at present the predominant approach for dense correspondence. It registers a reference model to a target model and then resamples the target according to the reference. non-rigid shape matching, we learn from examples a canon-ical transformation, i.e. a transformation from the points of a shape Mrepresented as a triangular mesh de?ned over a vertex set V M, to a canonical label set L. In Section3we will show how this can be used to obtain dense correspon-dences between non-rigid shapes. In this tutorial, we will give an overview of dense correspondence algorithms for aligning images from different scenes. We will survey a variety of representations, including pixels (SIFT flow, Non-Rigid Dense Correspondence), semantic segments (layer flow) and image pyramid (deformable spatial pyramid). Abstract. We describe a framework for registering a group of images together using a set of non-linear di#eomorphic warps. The result of the groupwise registration is an implicit definition of dense correspondences between all of the images in a set, which can be used to construct statistical models of shape change across the set, avoiding the need for manual annotation of training images. in a non-rigid dense correspondence (NRDC) algorithm, but it employs weak matching evidence that cannot guarantee reliable performance. Geometric in-variance to scale and rotation is provided by DAISY Filer Flow (DFF) [4], but its implicit smoothness constraint often induces mismatches. Recently, Ham et Dense Human Body Correspondences Using Convolutional Networks Lingyu Wei University of Southern California Most techniques are based on robust non-rigid surface estimating accurate dense correspondence between partial shapes, such as scans from a single RGB-D camera and ar- To establish dense correspondence across N faces, a random reference face is first selected. We align the keypoints of Voronoi Region V k 2 of an arbitrary face F 2 in the collection of N faces with the keypoints of the reference face Voronoi region V k 1. The alignment is non-rigid , and matches the shapes of the regions from the two faces Thus, non-expert readers can easily evaluate the quality of dense-correspondence morphometrics research by looking at the average surfaces, which are typically used in manuscript figures, with the In this tutorial, we will give an overview of dense correspondence algorithms for aligning images from different scenes.
