CONTENT-SPECIFIC IMAGE PROCESSING

摘要

An image analysis unit (200) for analyzing an input image (100) is disclosed. The image analysis unit (200) comprises: a linear filter (202) for filtering the input image (100) into a first filtered image; a nonlinear filter (204) for filtering the input image (100) into a second filtered image; and an output unit (206) for outputting an analysis output signal which is based on comparing the first filtered image with the second filtered image. Besides that, an image processing apparatus comprising an image enhancement unit for computing an output image on basis of an input image (100), wherein the enhancement unit is controlled by the analysis output signal of the image analysis unit (200), is disclosed.
