Template Based Shape Descriptor
نویسنده
چکیده
We introduce a new 3D shape descriptor which maps the surface features onto an arbitrary template surface using mean-value interpolation. A compact numerical shape descriptor is extracted using manifold harmonics on the template. We show that mean-value interpolation is a strong alternative to the often used projection. The utility of using different templates is established by showing that concatenating descriptors coming from different templates improves retrieval quality.

بازیابی مبتنی بر شکل اجسام با توصیفگرهای بدست آمده از فرآیند رشد کانتوری
In this paper, a novel shape descriptor for shape-based object retrieval is proposed. A growing process is introduced in which a contour is reconstructed from the bounding circle of the shape. In this growing process, circle points move toward the shape in normal direction until they get to the shape contour. Three different shape descriptors are extracted from this process: the first descript...
متن کاملMeaningful Correspondence, Local Contex and Shape Statistics in Deformable Templates
The paper presents a variational framework to compute first and second order statistics of an ensemble of shapes undergoing deformations. Geometrically “meaningful” correspondence between shapes is established via a kernel descriptor that characterizes local shape properties. Such a descriptor allows retaining geometric features such as high-curvature structures in the average shape, unlike con...
متن کاملAn Experimental Study on Various Combinations of Shape Descriptors and Matching Methods Applied in the General Shape Analysis Problem
The aim of the General Shape Analysis (GSA) is to find one or a few most similar general templates for a processed object — exact identification is not performed, but the general shape features are obtained. The GSA approach may be applied for coarse separation of objects in the database prior to their classification or in the case when the data are incomplete or there is a high variability wit...

متن کاملRecommendations to quantify villous atrophy in video capsule endoscopy images of celiac disease patients
AIM To quantify the presence of villous atrophy in endoscopic images for improved automation. METHODS There are two main categories of quantitative descriptors helpful to detect villous atrophy: (1) Statistical and (2) Syntactic. Statistical descriptors measure the small intestinal substrate in endoscope-acquired images based on mathematical methods. Texture is the most commonly used statisti...
