What is Butterworth High Pass filter?

In the field of Image Processing, Butterworth Highpass Filter (BHPF) is used for image sharpening in the frequency domain. Image Sharpening is a technique to enhance the fine details and highlight the edges in a digital image. It removes low-frequency components from an image and preserves high-frequency components.

What is digital Butterworth filter?

The Butterworth filter is a type of signal processing filter designed to have a frequency response that is as flat as possible in the passband. It is also referred to as a maximally flat magnitude filter.

What is digital high pass filter?

What is a High Pass Filter? A high-pass filter is an electronic filter that passes signals with a frequency higher than a certain cutoff frequency and attenuates signals with frequencies lower than the cutoff frequency. The attenuation for each frequency depends on the filter design.

Is Butterworth filter a digital filter?

Butterworth filters are one of the most commonly used digital filters in motion analysis. They are fast and simple to use.
