An Image Enhancement Method for Improving Small Intestinal Villi Clarity

no code implementations25 Feb 2024 Shaojie Zhang, Yinghui Wang, Peixuan Liu, Yukai Wang, Liangyi Huang, Mingfeng Wang, Ibragim R. Atadjanov

Subsequently, an adaptive light gain factor is generated based on the low-frequency component, and an adaptive gradient gain factor is derived from the convolution results of the Laplacian operator in different regions of small intestinal villi images.

An Error-Matching Exclusion Method for Accelerating Visual SLAM

no code implementations22 Feb 2024 Shaojie Zhang, Yinghui Wang, Jiaxing Ma, Wei Li, Jinlong Yang, Tao Yan, Yukai Wang, Liangyi Huang, Mingfeng Wang, Ibragim R. Atadjanov

In Visual SLAM, achieving accurate feature matching consumes a significant amount of time, severely impacting the real-time performance of the system.

A Feature Matching Method Based on Multi-Level Refinement Strategy

no code implementations21 Feb 2024 Shaojie Zhang, Yinghui Wang, Jiaxing Ma, Wei Li, Jinlong Yang, Tao Yan, Yukai Wang, Liangyi Huang, Mingfeng Wang, Ibragim R. Atadjanov

Feature matching is a fundamental and crucial process in visual SLAM, and precision has always been a challenging issue in feature matching.

A Robust Error-Resistant View Selection Method for 3D Reconstruction

no code implementations18 Feb 2024 Shaojie Zhang, Yinghui Wang, Bin Nan, Wei Li, Jinlong Yang, Tao Yan, Yukai Wang, Liangyi Huang, Mingfeng Wang, Ibragim R. Atadjanov

To address the issue of increased triangulation uncertainty caused by selecting views with small camera baselines in Structure from Motion (SFM) view selection, this paper proposes a robust error-resistant view selection method.

Region Feature Descriptor Adapted to High Affine Transformations

no code implementations15 Feb 2024 Shaojie Zhang, Yinghui Wang, Bin Nan, Wei Li, Jinlong Yang, Tao Yan, Yukai Wang, Liangyi Huang, Mingfeng Wang, Ibragim R. Atadjanov

To address the issue of feature descriptors being ineffective in representing grayscale feature information when images undergo high affine transformations, leading to a rapid decline in feature matching accuracy, this paper proposes a region feature descriptor based on simulating affine transformations using classification.

A Highlight Removal Method for Capsule Endoscopy Images

no code implementations11 Feb 2024 Shaojie Zhang, Yinghui Wang, Peixuan Liu, Wei Li, Jinlong Yang, Tao Yan, Yukai Wang, Liangyi Huang, Mingfeng Wang, Ibragim R. Atadjanov

The images captured by Wireless Capsule Endoscopy (WCE) always exhibit specular reflections, and removing highlights while preserving the color and texture in the region remains a challenge.
