Abstract

fetched live from OpenAlex

This study introduces and evaluates a new approach for the reconstruction of image sequences acquired during non destructive testing by pulsed thermography.The proposed method consists in applying two linear support vector regressions, to model the evolution of the data from both a spatial and temporal point of view.Each regressor will map the data with respectively the number of pixels and the number of frames using a convex optimization.Then the regressors are used to predict a more robust representation of the data which is thus used to reconstruct the sequence.The proposed method has been applied to data related to a reference sample of carbon reinforced fiber with known defects.This approach has given good results in terms of noise reduction as well as the quality of the reconstructed image than most of the state of the art methods.The proposed method was able to outperform many of the state of the art algorithms and give comparable results otherwise despite being sensitive to non-uniform heating.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
