Image Filter
The tool of Image filter is used to suppress the noise of the target image while reserving the image
detail features as much as possible.
Image Filter
Gaussian Filter
Gaussian filtering is a linear smoothing filter, and Gaussian smoothing filter is very
effective for suppressing noise that obeys a normal distribution.
Median Filter
Median filter is a non-linear smoothing filter, and it is used to eliminate salt and pepper
noise in the image. It can eliminate the noise while protecting the edge of the signal so that
it will not be blurred.
Mean Filter
Mean filter is a normalized filter, which has a good suppression effect on periodic
interference noise.
Inverse Filter
It inverts the target image grayscale.
Edge Extraction
It binarizes the edge image whose gradient magnitude is within the edge threshold range to
extract the edge.
If you want to recognize the first line of characters in the figure below, but because the characters
are composed of a dot matrix and the gray level difference is small, it is difficult to recognize. After
image binarization, corrosion, and Gaussian filtering, the second line of characters can be obtained.
