How to find panda in the blur image?
Following is a noised image with a panda in it, I will find the panda with image
processing method.
Fig 1.Original image(there is a panda figure in it)
Step 1.
Fourier transformation, then we get following frequent image:

Fig 2. Frequency image
Step 2:
We only use the part around with red rectangle, and set other part 0, like following
