ICA-ASIFT-Based Multi-Temporal Matching of High-Resolution Remote Sensing Urban Images

open access: yesCybernetics and Information Technologies, 2016
While SIFT (Scale Invariant Feature Transform) features are used to match High-Resolution (HR) remote sensing urban images captured at different phases with large scale and view variations, feature points are few and the matching accuracy is low ...

Automatic Matching of Multi-Source Satellite Images: A Case Study on ZY-1-02C and ETM+

open access: yesApplied Sciences, 2017
The ever-growing number of applications for satellites is being compromised by their poor direct positioning precision. Existing orthoimages, such as enhanced thematic mapper (ETM+) orthoimages, can provide georeferences or improve the geo-referencing ...

Fast Scale-Invariant Feature Transform on GPU

open access: yes, 2020
Feature extraction of high-resolution images is a challenging procedure in low-power signal processing applications. This thesis describes how to optimize and efficiently parallelize the scale-invariant feature transform (SIFT) feature detection algorithm and maximize the use of bandwidth on the GPUsubsystem.
