Silhouette Mapping
Recent image-based rendering techniques have shown success in approximating detailed models using sampled images over coarser meshes. One limitation of these techniques is that the coarseness of the geometric mesh is apparent in the rough polygonal silhouette of the rendering. In this paper, we present a scheme for accurately capturing the external silhouette of a model in order to clip the app...
متن کاملSilhouette estimation.
Silhouettes arise in a variety of imaging scenarios. Pristine silhouettes are often degraded via blurring, detector sampling, and detector noise. We present a maximum a posteriori estimator for the restoration of parameterized facial silhouettes. Extreme dealiasing and dramatic superresolution, well beyond the diffraction limit, are demonstrated through the use of strong prior knowledge.
متن کاملShape from inconsistent silhouette
Shape from Silhouette (SfS) is the general term used to refer to the techniques that obtain a volume estimate from a set of binary images. In a first step, a number of images are taken from different positions around the scene of interest. Later, each image is segmented to produce binary masks, also called silhouettes, to delimit the objects of interest. Finally, the volume estimate is obtained...
متن کاملObservations on Silhouette Sizes
Silhouettes have many applications in computer graphics such as non-photorealistic edge rendering, fur rendering, shadow volume creation, and anti-aliasing. The number of edges, s, in the silhouette of a model observed from a point is therefore useful in analyzing such algorithms. This paper examines, from a theoretical viewpoint, a menagerie of objects with interesting silhouettes (including t...
متن کاملKnowledge-Based Silhouette Detection
A general-purpose neural model that challenges image understanding is presented in this paper. The model incorporates accumulative computation, lateral interaction and double time scale, and can be considered as biologically plausible. The model uses at global time scale t and in form of accumulative computation all the necessary mechanisms to detect movement from the grey level change at each ...
