Study Notes

Frequencies of an image measure the amount of grey value change with distance.
High frequency components are edges and noise, while low frequency components are backgrounds.
High pass filters pass over high frequency components and reduce or eliminate low frequency components.
Low pass filters pass over low frequency components and reduce or eliminate high frequency components.
Blurring is a low-pass filtering used to reduce sharp transitions in intensity and remove noise.
Sharpening is a high-pass filtering used to highlight fine details in an image.
Unsharp masking subtracts a blurred version of the image from the original.
Nonlinear filters rearrange the order of pixels in the mask to produce the output pixel.
The primary application of nonlinear filters is in the enhancement of noisy images.
Median filter is one of the most common non-linear filters used in image processing.
