Modeling and Analysis of Optical Blur for Everyday Photography
Optical blur obscures image detail due to the camera's optics. The blur appearance depends on the scene's depth, wavelength, as well as the camera. The inference of such information --- optical calibration, image deblurring, and depth estimation -- is of great interest to computer vision. Existing …

Multiframe Superresolution Techniques For Distributed Imaging Systems
… images are generally under-sampled, degraded by optical and pixel blurs, and corrupted by measurement noise. We exploit diversities in the imaging channels, namely, the number of cameras, magnification, position, and rotation, to undo degradations. Using an iterative back-projection (IBP) …

Estimation de l'échelle absolue par vision passive monofocale et application à la mesure 3D de néoplasies en imagerie coloscopique
… vision describes monocular system for which optical parameters are fixed. Such optical systems are notably embedded within endoscopic systems used in colonoscopy. This minimally invasive technique allows endoscopists to explore the colon cavity and remove neoplasias (abnormal growths of …

The effects of electronic microscanning on infrared image aliasing and spaial resolution
Most modern infrared electro-optical imaging systems utilize staring imagers to acquire image data. Typical staring focal plane arrays contain a two-dimensional array of photodetectors. Each photodetector generates an electrical current or charge proportional to the number of photons striking its …
