A color transfer method is presented to give fused multiband nighttime imagery a natural daytime color appearance in a simple and efficient way. Instead of using the traditional nonlinear l space
the proposed method transfers the color distribution of the target image (daylight color image) to the source image (fused multiband nighttime imagery) in the linear YCBCR color space. The YCBCR transformation is simpler and more suitable for image fusion compared to the l conversion. The YCBCR transformation can be extended into a general formalism. And the paper mathematically proves that
for color transfer
using color spaces conforming to this general YC BCR space framework can produce same recoloring results as using the YCBCR space. Experimental results demonstrate that the YCBCR based color transfer method works surprisingly well for transferring natural color characteristics of daylight color images to false color fused multiband nighttime imagery
and moreover
can also be successfully applied to recoloring a variety of color images. 2010 SPIE.

We present a color transfer method
which is designed to give fused multiband nighttime imagery a natural daytime color appearance in a simple and efficient way. Instead of using traditional nonlinear la space
the proposed method transfers the color distribution of the target image (daylight color image) to the source image (fused multiband nighttime imagery) in a linear color space named ICBCR. The ICBCR transformation is simpler than the la conversion
moreover
the IC BCR space is easily extended to image fusion. Our experiments on infrared and visual images show that the ICBC R based color transfer method works surprisingly well for transferring natural color characteristics of daylight color images to false color fused nighttime imagery. 2009 IEEE.

The new design about a CW
digital all-solid-stated LD pumped Nd:YVO 4 controller is introduced. The stable output power of this digital laser controller which adopts Digital Signal Processor(TMS320C31) is approximately 20mW. The whole system is composed of constant- current source
protection circuit
pulse-width modulation circuit
Si-photo-detector and amplified circuit and Digital Signal Processor control system
etc. In terms of error deviation Based on nonlinear control curves of LD power output by Si-photo-detector
the region control can be obtained by means of the PID control algorithm in the software platform
that is
error amendment and high stability laser power output can be achieved. And the precision of temperature control can reduce from 0.2C to 0.04C. By adopted integral separated mode PID control algorithm
the LD output power instability ( %) down to 2%. By way of adopting the new digital design
the work to protect the laser diode
including the continuous adjustable output power with high accuracy and stability
is easily obtained. The internal-external modulation control of the laser power based on digital optical feedback can be accomplished with stable power output. At last
the bringing reasons of noise are analyzed and the solving methods are put forward in this paper.
