Abstract

fetched live from OpenAlex

Medical image interpretation is facing an important challenge resulting from the continuously increasing amount of imaging data. Innovations in medical image visualization are necessary to assist the radiologist in interacting and navigating effectively large multidimensional imaging sets. We propose a novel wavelet splatting approach for multiresolution 3-D visualization. Our method renders the context with a low resolution at first, and then subsequently, refines it progressively to attain full resolution, while ensuring that a specific region of interest is rendered at full resolution at all times. It is based on the splatting approach for its computational efficiency and uses the localization property of the wavelet transform to simultaneously render a full-resolution region of interest with a coarser context. Lighting calculations are used in the preprocessing stage to enhance the quality of the visualization. A special data structure that is based on a zero-tree model is used to manipulate the region of interest more easily. The speed-up achieved reaches a factor of 30 compared to the time needed to display the full-resolution data. By achieving effective 3-D rendering, we bring an element of solution to the problem of the image overload.

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.
