Conclusion
Results show that through the fusion of infrared and low-lightlevel images, the image resolution and the probability by which the scene objects were discovered and discriminated by human eyes can be increased significantly

Image fusion technology:
Image fusion is extraction favorable information in each channel which contains the same target, and finally integrated them into a high quality images

Advantages of fusion
Targets can be easily detected
How to improve the visual
Low light level imaging technology Infrared imaging technology Image fusion technology
Low-level-light technology :
Enhancing the light that the detector received to get clearer target image also called image enhancement technology.
Infrared technology :
Using infrared detector to receive the target’s infrared radiation so that we can detect the target.
What can we see in the dark or just with the light of stars ?
More details Good reliability Reduce redundant
Difficulties of fusion
Noises (fusion image will create more noises)
Registration is difficulties Algorithm is complicated Hardware implementation is complicated
Thanks for your listening
Everyone knows that the human eye can receive a lot of information, but from the view of the spectrum, what we see is a very narrow part of the full spectrum of nature (wavelength range 380nm-780nm ).Therefore, what we do is to broaden our horizons, let us see more and more clearly.
Fusion image
Pseudo fusion image
Steps to achieve image fusion
Step 1 : Pretreatment Step 2 : Registration Step 3 : Fusion
Pretreatment : unify resolution >> filtering >> digitization >> geometric transformation >> uniformization >> enhancement Image Registration is the basis of image fusion.

Nothing but noise
Not clearly
If we use infrared anwenku.baidu.com low-level-light detector, we can see more …
Infrared image
low light level image
As a result , infrared imaging technology make us see the invisible and low level light imaging technology make us see more clearly. so, naturally,we will think what will happen if we put them together?
