IMAGE PROCESSING METHOD WITH DETAIL-ENHANCING FILTER WITH ADAPTIVE FILTER CORE

摘要

The invention relates to an image processing method for filtering with an adaptive filter core size, characterized in that the following steps are included: (a) an original image is created, (b) an information measure is calculated on the basis of the original image, (c) a filter core size is calculated on the basis of the information measure, (d) the original image is low-pass filtered with an adaptive low-pass filter with filter core size to form a low-pass filtered image, (e) a high-pass filtered image is calculated by subtracting the low-pass filtered image from the original image, (f) a detail -enhanced image without light rings is obtained by a high-pass image scaled with a detail enhancement measure being added to the low-pass image. The invention additionally relates to an image processing device comprising an image recording device 11), an image processing unit (12), and an image display unit (13), in which: (a) the recording device (11) creates an original image, (b) an image processing unit (12) calculates an information measure on the basis of the original image, (c) an image processing unit (12) calculates a filter core size on the basis of the information measure, (d) the image processing unit (12) low-pass filters the original image with an adaptive low-pass filter with filter core size to form a low-pass filtered image, (e) the image processing unit (12) calculates a high-pass filtered image by subtracting the low-pass filtered image from the original image, (f) the image processing unit (12) calculates a detail -enhanced image without light rings by adding a high-pass image scaled with a detail enhancement measure to the low-pass image, (g) the image display unit (13) visualizes the detail- enhanced image without light rings.
