-This paper presents a radiation study on the pinned photodiode (PPD) and Transfer Gate (TG) of 4T (4 Transistor) CMOS Image Sensors (CIS). The PPD and the TG are the most sensitive elements for the sensor’s dark signal. The transfer gate length has an effect on the dark current due to the electric field variation in the transfer channel and the defect generation near the overlap region between...

Color images have a wider range of applications than gray images. There are two ways to extend the traditional super-resolution reconstruction method color images: Super resolution reconstructs each channel image individually; Change RGB bands into YCrCb bands, then luminance component and interpolates chrominance components.These algorithms cannot effectively utilize property that edges textur...

We consider a dark sector consisting of dark matter that is a Dirac fermion and a scalar mediator. This model has been extensively studied in the past. If the scalar couples to the dark matter in a parity conserving manner then dark matter annihilation to two mediators is dominated by the P -wave channel and hence is suppressed at very low momentum. The indirect detection constraint from the an...

many factors are involved in learning and memory processes including brain nuclei, neurotransmitter systems, and the activity of ion channels. studies showed inconsistent effects of calcium channel blockers on learning process, especially memory consolidation; however, little is known about their effect on memory acquisition and retrieval. accordingly, the present study aimed to determine the e...

Blind image deblurring is a long standing challenging problem in processing and low-level vision. Recently, sophisticated priors such as dark channel prior, extreme local maximum gradient have shown promising effectiveness. However, these methods are computationally expensive. Meanwhile, since involved subproblems cannot be solved explicitly, approximate solution commonly used, which limits the...

Luminance vision has high spatial resolution and is used for form vision and texture discrimination. In humans, birds and bees luminance channel is spectrally selective-it depends on the signals of the long-wavelength sensitive photoreceptors (bees) or on the sum of long- and middle-wavelength sensitive cones (humans), but not on the signal of the short-wavelength sensitive (blue) photoreceptor...
