A Robust Deep Learning Framework for Steganography in 1D and 2D Barcodes

Electronics Letters, Volume 62, Issue 1, January/December 2026.
Barcodes are a key IoT technology for product identification and supply chain traceability, yet they are limited in data capacity and security. To address these limitations, we propose a barcode steganography framework based on image embedding and deep learning.

AUTOMATIC RECTIFICATION OF BUILDING FAÇADES [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Focusing mainly on the case of (near-)planar building façades, a methodology for their automatic projective rectification is described and evaluated. It relies on a suitably configured, calibrated stereo pair of an object expected to contain a minimum of

Asteroid Pose Estimation Method Based on Monocular Vision and Intelligent Perception

Electronics Letters, Volume 62, Issue 1, January/December 2026.
This paper proposes a pose estimation network based on geometric perception dual branch regression heads. By jointly optimizing rotation (Euler angle) and translation parameters and combining physical constraints to improve solution accuracy, the network achieves high‐precision solution of asteroid relative pose with a position estimation error of less

Multi‐Camera Pairwise Calibration Through Joint Optimization Method

IET Image Processing, Volume 20, Issue 1, January/December 2026.
We propose a novel multi‐camera calibration method for systems with non‐overlapping fields of view. By establishing local constraints between adjacent cameras and performing staged joint optimization, our approach estimates intrinsic/extrinsic parameters while dynamically selecting optimal calibration paths via camera topology graphs and confidence ...
