Digital cameras: optical footprints in a performance metric

SPIE Proceedings, 2008
Conventional methods for objective measurement of the performance of image forming systems are reviewed. Due to the present widespread use of digital cameras, coupled with little data available on their actual performance, an alternative simpler approach for their comparative assessment has been studied. Camera performance, in this resolution-type test,

Automated Benchmarking and Monitoring of an Earthmoving Operation's Carbon Footprint Using Video Cameras and a Greenhouse Gas Estimation Model

Computing in Civil Engineering (2012), 2012
Benchmarking and monitoring are critical steps toward improving operational efficiency of earthmoving equipment and minimizing their environmental impacts. Despite the importance, the relationship between operational efficiency and total pollutant emissions of these operations has not been fully understood.

Multi-object triangulation and 3D footprint tracking for multi-camera systems

Anais Estendidos da XXXVIII Conference on Graphics, Patterns and Images (SIBGRAPI 2025)
This paper presents a method for 3D footprint triangulation and tracking of multiple objects from different classes using a multi-camera system with overlapping views. The proposed method is designed to operate in complex environments such as Intelligent Spaces, where localization of heterogeneous entities (e.g., humans, robots, and furniture) is ...
