Diffraction Prediction in HDR Measurements
(The Eurographics Association, 2017)
Modern imaging techniques have proved to be very efficient to recover a scene with high dynamic range values. However, this high dynamic range can introduce star-burst patterns around highlights arising from the diffraction ...
The Effects of Digital Cameras Optics and Electronics for Material Acquisition
(The Eurographics Association, 2017)
For material acquisition, we use digital cameras and process the pictures. We usually treat the cameras as perfect pinhole cameras, with each pixel providing a point sample of the incoming signal. In this paper, we study ...
