Non-associative Markov Networks for 3d Point Cloud Classification
The problem of laser scan analysis gained significant attention within the last decade. The standard approach to point cloud classification utilizes Markov Random Fields (MRF). Usually, a subclass of MRFs, Associative Markov Networks (AMNs), are used. In AMN the pairwise potential function is constant for a pair of different class labels. In some cases this constraint is too rigorous since it d...
متن کامل3D Point Cloud Classification and Segmentation using 3D Modified Fisher Vector Representation for Convolutional Neural Networks
The point cloud is gaining prominence as a method for representing 3D shapes, but its irregular format poses a challenge for deep learning methods. The common solution of transforming the data into a 3D voxel grid introduces its own challenges, mainly large memory size. In this paper we propose a novel 3D point cloud representation called 3D Modified Fisher Vectors (3DmFV). Our representation i...
متن کاملLearning 3D Point Cloud Histograms
In this paper we show how using histograms based on the angular relationships between a subset of point normals in a 3D point Cloud can be used in a machine learning algorithm in order to recognize different classes of objects given by their 3D point clouds. This approach extends the work done by Gary Bradski at Willow Garage on point clouds recognition by applying a machine learning approach t...
متن کامل3D Point Cloud Tree Modelling
Three-dimensional (3D) point cloud models of trees were developed using the software packages Maya and MATLAB. These models are to be assembled into a forest scene that can be used for producing simulated Laser Detection and Ranging (LADAR) imagery of objects obscured beneath the canopy. This document describes the approach for modelling the trees using Maya then importing and completely recons...
