Smoothing:
Smoothing is a process for reduces the noise contained in the image.
Most images tend to contain random noise. If an image containing noise is processed, the
noise is also treated as correct data, deteriorating the reliability of the measurement data
finally calculated. However, if tone differences are found at the CCD 1 pixel level, the 1 pixel
data may be eliminated by smoothing.
Median filter:
This is the processing method to reduce the noise included in an image.
When this method is used, the peripheral pixel values of the target pixel are obtained, the
pixel values are arranged in order of size, and the middle pixel value is set instead of the
target pixel value.
When you want to remove the spike noise, which is different in a great degree from the
peripheral pixel values, this method is effective.
Example of “Size: 3”
The peripheral pixel values of the target pixel value 1000 are
obtained.
When these values are arranged from the lowest in order, they
are arranged as shown below.
20, 30, 40, 50, 60, 70, 80, 90, 1000
The middle value is 60.
The middle value 60 is set instead of the target pixel value 1000.
As the [Size] parameter is larger, the peripheral pixels have larger influence and so the image
is blurred.
Gaussian filter:
This is the processing method to reduce the noise included in an image.
When this method is used, the peripheral pixel values of the target pixel are obtained, these
pixel values are weighted and the average of the weighted values is regarded as the target
pixel value.
When one pixel is near the target pixel, the value is close to the target pixel value. When
one pixel is far away from the target pixel, the value is different in a great degree from the
target pixel value. When one pixel is near the target pixel, a weight value is large. When it
is far away from the target pixel, a weight value is small.
This method is effective to remove noise in the image where similar strength noise is
scattered.
