CNNs based Viewpoint Estimation for Volume Visualization [article]

Neng Shi, Yubo Tao
2019 arXiv   pre-print
We also introduce a CNN feature-based image similarity measure for similarity voting based viewpoint selection, which can suggest semantically meaningful optimal viewpoints for different volumes and transfer  ...  Viewpoint estimation from 2D rendered images is helpful in understanding how users select viewpoints for volume visualization and guiding users to select better viewpoints based on previous visualizations  ...  Inspired by the similarity voting for viewpoint selection [38] , we propose a weighted probability voting for viewpoint selection.  ...

3D Object Recognition and Pose Estimation from Point Cloud using Stably Observed Point Pair Feature

Deping Li, Hanyun Wang, Ning Liu, Xiaoming Wang, Jin Xu
2020 IEEE Access  
Recently, the point pair features (PPF) voting approach has been shown to be effective for simultaneous object recognition and pose estimation.  ...  The stably observed point pairs are calculated from the partial view point clouds which are rendered by the virtual camera from various viewpoints.  ...  via a voting scheme that is similar to the generalized Hough transform.  ...

Multi-view Recognition Using Weighted View Selection [chapter]

Scott Spurlock, Hui Wu, Richard Souvenir
2015 Lecture Notes in Computer Science  
In this paper, we present an algorithm for multi-view recognition in a distributed camera setting that learns which viewpoints are most discriminative for particular instances of ambiguity.  ...  The main contribution is a locality-sensitive meta-training step to learn a disambiguation function to select the relative weighting of available viewpoints needed to classify a 2D input example.  ...  The basic classifier where the SVM is trained with the base kernel without respect to viewpoint. SVM Voting (vote).  ...

Image-based TF colorization with CNN for direct volume rendering

Seokyeon Kim, Yun Jang, Seung-Eock Kim
2021 IEEE Access  
Ma and Entezari [48] have shown a technique to identify FOI (Feature of Intensity) utilizing the cell-based feature similarity and automatically generate the TF based on the selected feature.  ...  We introduce the voting system for the TF labeling with Borda count in Section IV-B to prevent the system from partially mislabeling by searching for the best label from labels in 26 different viewpoints  ...

Viewpoint-independent object class detection using 3D Feature Maps

Joerg Liebelt, Cordelia Schmid, Klaus Schertler
2008 2008 IEEE Conference on Computer Vision and Pattern Recognition  
Most existing approaches recognize object classes for a particular viewpoint or combine classifiers for a few discrete views.  ...  For recognizing an object class in an image we match the synthetic descriptors to the real ones in a 3D voting scheme.  ...  For each model, its minimum-volume enclosing rectangular bounding box is computed from its mesh geometry.  ...

Gen6D: Generalizable Model-Free 6-DoF Object Pose Estimation from RGB Images [article]

Yuan Liu and Yilin Wen and Sida Peng and Cheng Lin and Xiaoxiao Long and Taku Komura and Wenping Wang
2022 arXiv   pre-print
Gen6D consists of an object detector, a viewpoint selector and a pose refiner, all of which do not require the 3D object model and can generalize to unseen objects.  ...  In Gen6D, we design a novel viewpoint selector to pixel-wisely compare two images to select viewpoint and a novel volume-based pose refiner which iteratively refines the pose without rendering new images  ...  +DeepIM Ref." means using the refiner DeepIM[28]to refine the pose for one step. "+Volume Ref." means refinement with our volume-base refiner for one step.  ...
