Rapid imaging in the field followed by photogrammetry digitally captures the otherwise lost dimensions of plant specimens. [PDF]
Appl Plant Sci, 2023 Abstract Premise We recognized the need for a customized imaging protocol for plant specimens at the time of collection for the purpose of three‐dimensional (3D) modeling, as well as the lack of a broadly applicable photogrammetry protocol that encompasses the heterogeneity of plant specimen geometries and the challenges introduced by processes such as

SfM-3DULC: Reliability of a new 3D wound measurement procedure and its accuracy in projected area. [PDF]
Int Wound J, 2022 Abstract Three‐dimensional (3D) wound measurement lacks a gold standard to test accuracy. It is useful to develop procedures to scan wounds and reconstruct their 3D model with low‐cost techniques. We present a new procedure (Structure from Motion [SfM]‐3DULC) that uses photographs for measuring nine wound variables.

Optimization of a biometric system based on acoustic images. [PDF]
ScientificWorldJournal, 2014 On the basis of an acoustic biometric system that captures 16 acoustic images of a person for 4 frequencies and 4 positions, a study was carried out to improve the performance of the system. On a first stage, an analysis to determine which images provide more information to the system was carried out showing that a set of 12 images allows the system to
