1. A system for processing an object edge of an image input, comprising: an edge filter having a configuration to process the image input and having a communication path to provide generated edge data in accordance with the object edge of the image input; a first edge-smoothing filter with an arrangement to receive and process the edge data to filter-out image noise while preserving the object edge of the image input, and with an output to provide generated first edge-smoothed data; a gain amplifier coupled after the first edge-smoothing filter; a second edge-smoothing filter with an arrangement to receive and process the amplified first edge-smoothed data to filter-out image noise while preserving the object edge of the image input, and with an output to provide generated second edge-smoothed data; and an adder coupled to receive and configured to add the second edge-smoothed data to the image input, thereby generating an edge-smoothed image; wherein the edge filter, the first edge-smoothing filter, the gain amplifier and the second edge-smoothing filter are electrically connected in series.
