Rad Tolerant CMOS Image Sensor Based on Hole Collection 4T Pixel Pinned Photodiode [PDF]

open access: yes, 2012
1.4μm pixel pitch CMOS Image sensors based on hole collection pinned photodiode (HPD) have been irradiated with 60Co source. The HPD sensors exhibit much lower dark current degradation than equivalent commercial sensors using an Electron collection ...

Pixel Crosstalk and Correlation with Modulation Transfer Function of CMOS Image Sensor [PDF]

open access: yes, 2005
The Modulation Transfer Function is a common metric used to quantify image quality but inter-pixel crosstalk analysis is also of interest. Because of an important number of parameters influencing MTF, its analytical calculation and crosstalk ...

Region-based multimodal image fusion using ICA bases [PDF]

open access: yes, 2006
In this paper, we present a novel multimodal image fusion algorithm in the independent component analysis (ICA) domain. Region-based fusion of ICA coefficients is implemented, where segmentation is performed in the spatial domain and ICA coefficients ...

Surface projection for mixed pixel restoration [PDF]

open access: yes, 2009
Amplitude modulated full-field range-imagers are measurement devices that determine the range to an object simultaneously for each pixel in the scene, but due to the nature of this operation, they commonly suffer from the significant problem of mixed ...
