Abstract:
1. A probe for determining image blurriness comprising: a first set of edge filters configured to detect fast edges within an input image to produce a plurality of fast edge filter outputs; a second set of edge filters configured to detect slow edges within the input image to produce a plurality of slow edge filter outputs; a first summation circuit configured to combine the fast edge filter outputs to produce a fast edge filter output array; a second summation circuit configured to combine the slow edge filter outputs to produce a slow edge filter output array; circuitry configured to decimate the fast edge and the slow edge filter output arrays separately to produce a decimated fast edge filter array and a decimated slow edge filter array; and circuitry configured to process the respective decimated fast edge and slow edge filter arrays to generate a localized maximum sharpness value as a measure of the blurriness of the input image.
