Tracking Group Targets Using Hypergraph Matching in Data Association
This paper reformulates the traditional MTT data association problem as an hypergraph matching one between the hypergraphs formed from tracks and observations, and shows that the traditional approach which is…

A Single Algorithm Combining Exposure and Focus Fusion
This paper proposes an overhauled method of exposure fusion that solves the exposure and focus problems simultaneously, achieving a well-exposed, all-in-focus result.

A Graph Traversal Based Algorithm for Obstacle Detection Using Lidar or Stereo
We present a novel computationally efficient approach to obstacle detection that is applicable to both structured and unstructured environments.
-
Transverse Mercator with an Accuracy of a Few Nanometers
Implementations of two algorithms for the transverse Mercator projection are described; these achieve accuracies close to machine precision.
-
3D Alignment and Change Detection from Uncalibrated Eye Images
We introduce a projective geometry based approach that reconstructs and aligns 3D blood vessel networks given two stereo pairs of optic disc images.

Method of Image Fusion and Enhancement Using Mask Pyramid
We proposed an algorithmic approach using a mask pyramid to better localize the selection process. A new embedded system architecture that builds upon the Acadia ® II Vision Processor is…
-
Mask Pyramid Methodology for Enhanced Localization in Image Fusion and Enhancement
The proposed approach offers a generic methodology for applications in image enhancement, high dynamic range compression, depth of field extension, and image blending.

High-Precision Localization Using Visual Landmarks Fused with Ranged Data
In this paper, we demonstrated that with the use of precise 3D Li-dar range data, we are able to build a global consistent database of high precision 3D visual landmarks,…
