3D landmark model discovery from a registered set of organic shapes

Abstract: We present a machine learning framework that automatically generates a model set of landmarks for some class of registered 3D objects: here we use human faces. The aim is to replace heuristically-designed landmark models by something that is learned from training data. The value of this automatically generated model is an expected improvement in robustness and precision of learning-based 3D landmarking systems. Simultaneously, our framework outputs optimal detectors, derived from a prescribed pool of surface d… Show more

“…Mean, Gaussian, principal curvatures, shape index, and curvedness, evaluated with varying neighbourhood size and bin size, were adopted as descriptors by Creusot et al to support keypoints detection on 3D faces. LDA was employed to define weights to combine matching score maps over a population of neighbouring and nonneighbouring vertices, relative to the relevant landmark, and experiments were carried out on FRGC v2 [22] and BFM database [23]. Histograms of shape index (HoS) with 8 bins, the shape index itself, and principal curvatures were used to develop a mesh-based method for 3D facial expression recognition to be tested on BU3D-FE [24] [25] [26] and Bosphorus [27] databases.…”
