Hough Pyramid Matching: Speeded-Up Geometry Re-ranking for Large Scale Image Retrieval [PDF]
International Journal of Computer Vision, 2013 Exploiting local feature shape has made geometry indexing possible, but at a high cost of index space, while a sequential spatial verification and re-ranking stage is still indispensable for large scale image retrieval. In this work we investigate an accelerated approach for the latter problem.

PSPNet-SLAM: A Semantic SLAM Detect Dynamic Object by Pyramid Scene Parsing Network
IEEE Access, 2020 Simultaneous Localization and Mapping (SLAM) plays an important role in the computer vision and robotic field. The traditional SLAM framework adopts a strong static world assumption for convenience of analysis.

Accelerating X-Ray Data Collection Using Pyramid Beam Ray Casting Geometries [PDF]
IEEE Transactions on Image Processing, 2011 Image reconstruction from its projections is a necessity in many applications such as medical (CT), security, inspection, and others. This paper extends the 2-D Fan-beam method in [2] to 3-D. The algorithm, called Pyramid Beam (PB), is based upon the parallel reconstruction algorithm in [1]. It allows fast capturing of the scanned data, and in 3-D, the

Self-Adaptive Grinding for Blind Tip Reconstruction of AFM Diamond Probe
Nanotechnology and Precision Engineering, 2018 : Blind tip reconstruction (BTR) method is one of the favorable methods to estimate the atomic force microscopy (AFM) probe shape. The exact shape of the characterizer is not required for BTR, while the geometry of the sample may affect the ...

Combinatorial Pyramids and Discrete Geometry for Energy-Minimizing Segmentation [PDF]
, 2006 This paper defines the basis of a new hierarchical framework for segmentation algorithms based on energy minimization schemes. This new framework is based on two formal tools. First, a combinatorial pyramid encode efficiently a hierarchy of partitions. Secondly, discrete geometric estimators measure precisely some important geometric parameters of the ...
