From Face Images and Attributes to Attributes
The face is an important part of the identity of a person. Numerous applications benefit from the recent advances in prediction of face attributes, including biometrics (like age, gender, ethnicity) and accessories (eyeglasses, hat). We study the attributes’ relations to other attributes and to face images and propose prediction models for them. We show that handcrafted features can be as good ...
متن کاملUnderstanding Higher-Order Shape via 3D Shape Attributes
In this paper we investigate 3D shape attributes as a means to understand the shape of an object in a single image. To this end, we make a number of contributions: (i) we introduce and define a set of 3D shape attributes, including planarity, symmetry and occupied space; (ii) we show that such properties can be successfully inferred from a single image using a Convolutional Neural Network (CNN)...
متن کاملConstruction of 3D volumetric shape model from 2D US images
The current medical and engineering technologies help us in various fields of surgeries such as surgical simulations, preoperative plannings, intraoperative supports, and diagnostic explanations. In preoperative plannings, the simulation model of the target organ is necessary, and it is usually made from fine images that are obtained by some imaging devices such as CT (Computed Tomography) or M...
متن کامل3D Fundus Shape Reconstruction and Display From Stereo Fundus Images
I I A new method to recover and display 3D fundus lobictkn ~ow"w*n shape, inner bottom shape of eyeball, from stereo fundus image pair is developed. For the fundus stereo images, a simple stereo technique does not work, because the fundus is observed through eye lens and a contact wide-angle enlarging lens. In this yf lvLq: method, utilizing the fact that fundus forms a part of sphere, we ident...
متن کاملTowards 3D Reconstruction of Endoscope Images using Shape from Shading
The 3D Reconstruction problem from a single endoscope image of a smooth object is studied in the context of the Shape from Shading methods and considering a single light source at the camera projection center. Based on a curve expansion Shape from Shading algorithm, a spherical projection model for the endoscope camera and a dichromatic model for the surface reflectance, an approach to solve pr...
