An HDR imaging method with DTDI technology for push-broom cameras

Photonic Sensors, 2017
Conventionally, high dynamic-range (HDR) imaging is based on taking two or more pictures of the same scene with different exposure. However, due to a high-speed relative motion between the camera and the scene, it is hard for this technique to be applied
