US Patent:

20160014300, Jan 14, 2016

Filed:

Sep 25, 2015

Appl. No.:

14/865213

Inventors:

- Lexington KY, US
Michael Jo Phelps - Lexington KY, US

International Classification:

H04N 1/40
G06K 9/34
G06T 7/00
G06T 5/00
G06T 5/40

Abstract:

Systems and methods convert to binary an input image having pixels defining text and background. Thresholds are determined by which pixels in the input image and a corresponding blurred image will be defined as either binary black or binary white. Thresholds derive from grouped together neighboring pixels having pixels separated out that correspond to the background. For pixels of the input image defined as binary black and having corresponding pixels in the blurred image defined as binary black relative to their thresholds, those are set to black in the binary image, else they are set white. Techniques for devising thresholds, blurring images, grouping together pixels, statistical analysis, etc., typify the embodiments.
