A 5000 Fps, 4 Megapixel, Radiation-Tolerant, Wafer-Scale CMOS Image Sensor for the Direct Detection of Electrons and Photons [PDF]

open access: yesSensors
We present the design and characterisation of a 4.2-megapixel, wafer-scale CMOS image sensor, achieving over 5000 frames per second at full resolution. The sensor has a pixel pitch of 58 µm square pixels, thus being as large as a full 200 mm wafer.

Improving Generative Adversarial Networks for Patch-Based Unpaired Image-to-Image Translation

open access: yesIEEE Access, 2023
Deep learning models for image segmentation achieve high-quality results, but need large amounts of training data. Training data is primarily annotated manually, which is time-consuming and often not feasible for large-scale 2D and 3D images.
