Split edge enhancement architecture

A system comprising:

• a detail edge enhancer that comprises a first filter, a first noise reducer, a first gain multiplier, a second filter, a second noise reducer, a second gain multiplier and a first adder, wherein:
• (i) the detail edge enhancer is configured to receive a video signal that includes a plurality of fine detail edges,
• (ii) the first filter, first noise reducer, and the first gain multiplier are configured to enhance the plurality of fine detail edges of the received video signal horizontally to create a horizontal output signal, wherein the first noise reducer is configured to subtract a noise threshold from a noise level of the received video signal,
• (iii) the second filter, second noise reducer, and the second gain multiplier are configured to enhance the plurality of fine detail edges of the received video signal vertically to create a vertical output signal, and
• (iv) the first adder is configured to combine the horizontal output signal and the vertical output signal to generate a combined output signal;
• an edge map generator that comprises a pixel differentiator, an expander, and a threshold generator, wherein the pixel differentiator, the expander, and the threshold generator are configured to create an edge map of the received video signal;
• a second adder configured to combine the combined output signal with the edge map to generate a detail enhanced video signal;
• a first scaler configured to scale the detail enhanced video signal;
• and
• a transition enhancer configured to apply transition improvement to a plurality of transitions in the scaled video signal.
