Abstract

fetched live from OpenAlex

In this paper, we present a computationally efficient implementation of multi-spectral HDR (High Dynamic Range) image fusion on a Field Programmable Gate Array (FPGA), where an infrared HDR image stream is fused with a visible light HDR image stream. Each HDR frame in the video is composited from a set of differently exposed images of the same subject matter. This system runs in real-time and captures high-quality video for rugged industrial environments with difficult lighting conditions and fugitive dust/soot (e.g. in underground coal mining or arc welding). Firstly, the visible sensor is configured to stream video frames with alternated exposures. These differently exposed images are quantigraphically composited using an efficient implementation [1]. Then, the infrared image from a different sensor is synchronized and geometrically transformed to match the frames from the visible light sensor. Finally, the system fuses the HDR infrared video stream with the visible light HDR video stream to produce the output.

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.

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.
