Abstract

fetched live from OpenAlex

Deep neural networks (DNNs) have become a driving factor of visual scene understanding. However, the shortage of construction training images has been a major barrier to fully leverage its maximum performance potential. To address this issue, we investigate the effectiveness of synthetic images on DNN training in a common real-world scenario where only a small, biased real training image dataset is available. To this end, we synthetize numerous construction training images and conduct a DNN training experiment in real construction settings. Results show that the combined dataset-trained model always outperforms the one trained with only a small, biased real dataset. This finding indicates that an image synthetization approach has promising potential to enhance a given real training dataset in terms of data quantity and diversity. Image synthetization with automated labeling will mitigate the training image shortage, contributing to the development of more accurate and scalable DNNs for construction scene understanding.

Full frame distilled prediction

Teacher imitation

Not 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.
