When a digital medical image is enhanced, the useful details of the image should be strengthened, but the details cannot be strengthened by these algorithms based on traditional illumination-reflection model. According to the imaging principle and medical requirement, wavelet illumination-reflection model and a new algorithm based on the model are proposed. The image is decomposed into illumina...

The light-emitting diode (LED) is the main lighting solution currently adopted in aircraft cabin lighting. This technology offers high durability, energy efficiency and luminosity, bringing plenty of benefits for being utilized an aircraft. Despite its initial price, it has many advantages, operational cost lower than other types illumination, such as fluorescent lamps. Additionally, LED illumi...

What we believe to be a new illumination scheme that achieves space invariance and permits analytical determination of the image intensity distribution is proposed for partially coherent imaging systems. No additional lenses are needed for phase correction in front of the object and no restriction on illumination coherence is required. Conditions on the axial placement of the condenser with res...

We propose to enhance the performance of localized plasmon structured illumination microscopy (LP-SIM) via intensity correlations. LP-SIM uses sub-wavelength patterns encode high spatial frequency information. It can resolution up three-fold before gaps in OTF support arise. For blinking fluorophores or for quantum antibunching an correlation analysis induces higher harmonics pattern and enlarg...
