USE OF HISTORICAL AERIAL IMAGES FOR 3D MODELLING OF GLACIERS IN THE PROVINCE OF TRENTO by D. Poli, C. Casarotto, M. Strudl, E. Bollmann, K. Moe, K. Legat

“…Due to local radiometric saturation in a large part of the glacial surfaces and other disturbances affecting the historical images (e.g. scratches, scanning errors, dark shadows), dense image matching did not produce any valuable results, and stereo plotting could be used only on images (or image parts) with acceptable quality. …”

A Qualitative and Quantitative Analysis of Research in Mobility Technologies for Visually Impaired People by Jyoti Madake, Shripad Bhatlawande, Anjali Solanke, Swati Shilaskar

“…The survey findings reveal that optical and sonic sensor-based aids prioritize speed, weight, and battery life but lack major functionalities, achieving an average performance score of 62%. Stereo, monocular, SLAM, and 3-D point cloud-based aids excel in obstacle distance estimation and avoidance but require greater memory resources, with a lower performance score of 41%. …”
