3D Segmentation of Rodent Brain Structures Using Hierarchical Shape Priors and Deformable Models
In this paper, we propose a method to segment multiple rodent brain structures simultaneously. This method combines deformable models and hierarchical shape priors within one framework. The deformation module employs both gradient and appearance information to generate image forces to deform the shape. The shape prior module uses Principal Component Analysis to hierarchically model the multiple...
متن کاملestimation of depth and shape of subsurface cavities via multi adaptive neuro-fuzzy interference system using gravity data
in common classical methods of cavity depth estimation through microgravity data, usually when a pre-geometrical model is considered for the cavity shape, the simple geometrical models of sphere, vertical cylinder and horizontal cylinder are commonly used. it is obviously an important fact that in real conditions the shapes of the cavities are not exactly sphere, horizontal cylinder or vertical...
متن کاملMultiscale Shape Priors for 3D Branching Structures in Vasculature Segmentation
In this paper we present a multiscale non-parametric shape model for the segmentation of 3D branching structures such as vasculature or biological neuronal networks. The proposed technique models these structures as surfaces formed by varying-sized interconnected cylinders using higher order active contours. A geometric shape model is built using this approach and incorporated into a surface es...
متن کاملTarget Shape Classification Using Electromagnetic Induction Sensor Data
Classification based on shape is central to the problem of discriminating between unexploded ordnance (UXO) and clutter. Most UXO fit a specific profile: they are long and slender with typical length-to-diameter aspect ratios of four or five. Most clutter items, on the other hand, do not fit this profile. Using electromagnetic induction (EMI) sensor data, we present a model-based estimation pro...
متن کاملSurface reconstruction using local shape priors
We present an example-based surface reconstruction method for scanned point sets. Our approach uses a database of local shape priors built from a set of given context models that are chosen specifically to match a specific scan. Local neighborhoods of the input scan are matched with enriched patches of these models at multiple scales. Hence, instead of using a single prior for reconstruction, o...
