high-pass filter
high-pass filter In remote sensing, a type of spatial-frequency filter which selectively removes low spatial-frequency data from an image and increases contrast between high spatial-frequency data. The result is that the lines which make up the edges of objects are more clearly defined. High-pass filters are used to achieve edge enhancement.
