Being an efficient method of information fusion
image fusion has been used in many fields such as machine vision
medical diagnosis
military applications and remote sensing.In this paper
Pulse Coupled Neural Network (PCNN) is introduced in this research field for its interesting properties in image processing
including segmentation
target recognition et al.
and a novel algorithm based on PCNN and Wavelet Transform for Multi-focus image fusion is proposed. First
the two original images are decomposed by wavelet transform. Then
based on the PCNN
a fusion rule in the Wavelet domain is given. This algorithm uses the wavelet coefficient in each frequency domain as the linking strength
so that its value can be chosen adaptively. Wavelet coefficients map to the range of image gray-scale. The output threshold function attenuates to minimum gray over time. Then all pixels of image get the ignition. So
the output of PCNN in each iteration time is ignition wavelet coefficients of threshold strength in different time. At this moment
the sequences of ignition of wavelet coefficients represent ignition timing of each neuron. The ignition timing of PCNN in each neuron is mapped to corresponding image gray-scale range
which is a picture of ignition timing mapping. Then it can judge the targets in the neuron are obvious features or not obvious. The fusion coefficients are decided by the compare-selection operator with the firing time gradient maps and the fusion image is reconstructed by wavelet inverse transform. Furthermore
by this algorithm
the threshold adjusting constant is estimated by appointed iteration number. Furthermore
In order to sufficient reflect order of the firing time
the threshold adjusting constant is estimated by appointed iteration number. So after the iteration achieved
each of the wavelet coefficient is activated. In order to verify the effectiveness of proposed rules
the experiments upon Multi-focus image are done. Moreover
comparative results of evaluating fusion quality are listed. The experimental results show that the method can effectively enhance the edge details and improve the spatial resolution of the image. 2011 SPIE.

In the modern military affairs
especially in the complex field
the acquirement of real-time battlefield information and intelligence is getting more and more important
most of this work is completed by aerial reconnaissance or aerial mapping equipment. Aerial mapping camera
with time-sensitive and flexible features
is playing an increasingly important role in modern warfare. With the development of technology
aerial mapping camera has also gone through several generations
gradually from film-based type to transmission type. The theory and composition of domestic and international typical aerial mapping camera is introduced from the development situation and trend in this paper. Finally
with the domestic research status
the development trend of aerial mapping camera is proposed. 2011 IEEE.

We have investigated the effect of transparent thin film while mapping its surface profile by using vertical scanning white light interferometer. Our theory analysis showed that multiple reflections taking place within the transparent thin film result in an extra phase change. The simulation and experiment results revealed that this extra phase change is also related to the thickness of thin film
the numerical number of microscope interferometer objective and the spectral distribution of light source. As a result of extra phase change
the interferogram has some deviation in its shape or two interference fringes may appears while the thickness of thin film is large.
