WebOct 24, 2024 · High pass filters (Edge Detection, Sharpening) : High-pass filter can be used to make an image appear sharper. These filters emphasize fine details in the image – the opposite of the low-pass filter. High-pass filtering works in the same way as low-pass filtering; it just uses a different convolution kernel. WebGaussian Lowpass Filters: The transfer function of a Gaussian lowpass filter is defined as: (8) 3.1.2 Highpass filters (sharpening) A high-pass filter is a filter that passes high frequencies well, but attenuates frequencies lower than the cut-off frequency. Sharpening is fundamentally a highpass operation in the frequency domain.
