Dynamic Guided Multimodal Entity Alignment Based on Image Confidence [PDF]

Jisuanji gongcheng
Multimodal entity alignment identifies entities across different knowledge graphs that refer to the same real-world object and integrates these knowledge graphs. However, the inherent noise present in images, which are critical carriers of information in

Fundamental Limits in Multi-Image Alignment [PDF]

IEEE Transactions on Signal Processing, 2016
The performance of multi-image alignment, bringing different images into one coordinate system, is critical in many applications with varied signal-to-noise ratio (SNR) conditions. A great amount of effort is being invested into developing methods to solve this problem. Several important questions thus arise, including: Which are the fundamental limits

Calibration Alignment Sensitivity in Corneal Terahertz Imaging

Sensors, 2022
Improving the longitudinal modes coupling in layered spherical structure contributes significantly to corneal terahertz sensing, which plays a crucial role in the early diagnosis of cornea dystrophies. Using a steel sphere to calibrate reflection from the cornea sample assists in enhancing the resolution of longitudinal modes.
