Geometric features for voxel-based surface recognition
We introduce a library of geometric voxel features for CAD surface recognition/retrieval tasks. Our features include local versions of the intrinsic volumes (the usual 3D volume, surface area, integrated mean and Gaussian curvature) and a few closely related quantities. We also compute Haar wavelet and statistical distribution features by aggregating raw voxel features. We apply our features to...
متن کاملDeforming Surface Features Lines in Intrinsic Coordinates
Significant local structure of terrain surfaces can be described by structural lines which are connected sets of points where the surface is approximately cylindrical, i.e., the ratio of the principal curvatures is large. At each point curvature is maximal in the curvature direction associated with the curvature with larger absolute value. These lines form the skeleton of the surface for constr...
متن کاملVoxel-based surface area estimation: from theory to practice
Consider a complex, highly convoluted three dimensional object that has been digitized and is available as a set of voxels. How can one estimate the (original, continuous) area of a region of interest on the surface of the object? The problem appears in the analysis of segmented MRI brain data and in other three dimensional imaging applications. Several difficulties arise. First, due to the com...
متن کاملIntrinsic dependencies of CT radiomic features on voxel size and number of gray levels.
PURPOSE Many radiomics features were originally developed for non-medical imaging applications and therefore original assumptions may need to be reexamined. In this study, we investigated the impact of slice thickness and pixel spacing (or pixel size) on radiomics features extracted from Computed Tomography (CT) phantom images acquired with different scanners as well as different acquisition an...
