The paper introduces the Exponential Pixelating Integral (EPI) transform, which enhances pixel intensities in chest X‑rays to mitigate low‑contrast and noise issues. The enhanced images are polar‑transformed and represented using locally invariant Mandelbrot and Julia fractal geometries, producing dual fractal features. These features are classified with non‑parametric multivariate adaptive regression splines, achieving high accuracy (98.46–99.45%) and F1 scores (96.53–98.10%) on large benchmark datasets.

The article presents a comparative study of convolutional neural network (CNN) architectures for classifying COVID-19 from healthy lung images using CT and X‑ray scans. Multiple pre‑trained models—including VGG, DenseNet, ResNet, MobileNet, Xception, Inception, EfficientNet, and NasNet—were evaluated on two X‑ray and two CT datasets. ResNet and VGG achieved the highest accuracies, ranging from 95% to 98%, outperforming previous reports in the literature.

The CXR‑LT 2026 Challenge introduces a multi‑center, long‑tailed chest X‑ray classification benchmark with over 145,000 radiologist‑annotated images from PadChest and NIH datasets. It defines two core tasks: robust multi‑label classification on 30 known classes and open‑world generalization to 6 unseen rare disease classes. The paper outlines data collection, annotation, solution strategies, and evaluates performance across head‑vs‑tail, calibration, and cross‑center gaps, noting that vision‑language models improve in‑distribution and zero‑shot performance but rare‑finding detection under multi‑center shift remains difficult.

GRIPNet is a new CT‑based pulmonary nodule detector that incorporates a Gaussian radial intensity prior, reflecting the regular pattern of intensity peaks at nodule centers and Gaussian decay outward. By replacing generic square convolutions with pinwheel, dual‑frequency, dilated masked attention, and an adaptive loss, the network aligns each module with measurable intensity properties. The method achieves state‑of‑the‑art mAP@0.5 scores of 95.3%, 91.6%, and 97.9% on KanserSet, LUNA16, and Lung‑PET‑CT‑Dx, respectively, while maintaining real‑time speed and improving high‑IoU localization.
