Abstract

fetched live from OpenAlex

We investigate the image super-resolution problem by considering the power savings and performance improvement in image acquisition devices. Toward this end, we develop a deep learning based reconstruction network for images compressed using hardware-based downsampling, bit truncation and JPEG compression, which to our best knowledge, is the first work proposed in the literature. This is motivated by the fact that binning and bit truncation can be performed on the commercially available image sensor itself and results in a huge reduction in raw data generated by the sensor. The combination of these steps will lead to high compression ratios and significant power saving with further advantages of image acquisition simplification. Bearing these concerns in mind, we propose LISR-net (Lossy Image Super-Resolution network) which provides better image restoration results than state-of-the-art super resolution networks under hardware constraints.

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.
