A SWIR hyperspectral imaging system for art history and art conservation
Bibliographic record
Abstract
PRISMS is a portable hyperspectral imaging system designed for high resolution, in situ, remote imaging of paintings at inaccessible heights from the ground level. It currently operates from 400nm to 1700nm to provide detailed conservation monitoring, material identification and to assist art historical investigations for wall paintings. The system can be fitted with a variety of imagers to operate in the visible, near infrared and short wave infrared at close range and remotely. This talk will focus on the SWIR (short wave infrared) hyperspectral imager and its applications in art history and art conservation. The filtering system in the SWIR is based on an AOTF (acousto-optical tunable filter) system developed by Gooch & Housego that operates between 900nm and 1700nm which provides fast switching between the spectral bands as well as full flexibility in terms of central wavelength and bandwidth of the filters. Applications in imaging of underdrawings (preparatory sketches) beneath oil paintings and identification of paint materials will be presented.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
