Video processing system having a filter circuit with a spatial-frequency high-pass filter characteristic |
摘要 |
A video processing system, of the type used for portraying x-ray images, has a filter circuit with a spatial-frequency high-pass filter characteristic, the filter circuit including an amplitude-dependent separating filter having outputs to which respective spatial-frequency high-pass filters having different limit frequencies and/or having different kernel sizes are connected. The spatial-frequency high-pass filters are connected to the output of the overall filter circuit through an addition unit, so that the respective outputs of the spatial-frequency high-pass filters can be combined in different amounts to form the output of the overall filter circuit.
