System and method for identification and separation of form and feature elements from handwritten and other user supplied elements
First Claim
1. A computer implemented method for conducting progressive feature evaluation to identify a feature of interest in a document, the method comprising:
- receiving, by a processor, a document image and storing the document image in a memory coupled with the processor;
identifying, by the processor, a first pixel of the stored document image having a first characteristic;
defining, by the processor, a neighborhood of pixels of the stored document image, wherein the neighborhood of pixels includes one or more additional pixels having the first characteristic and being within a threshold distance of the first pixel or any of the one or more additional pixels;
defining, by the processor, an area including the defined neighborhood of pixels;
identifying, by the processor, an aspect ratio of the defined area; and
comparing the identified aspect ratio to one or more defined aspect ratios stored in a memory coupled with the processor, wherein the one or more defined aspect ratios correspond to one or more features, and determining the feature of the one or more features corresponding to the identified aspect ratio.

Abstract
A system and methods for progressive feature evaluation of an electronic document image to identify user supplied elements is disclosed. The system includes a controller in communication with a storage device configured to receive and accessibly store a generated plurality of candidate images. The controller is operable to analyze the electronic document image to identify a first feature set and a second feature set, wherein each of the first and second feature sets represent a different form feature, compare the first feature set to the second feature set, and define a third feature set based on the intersection of the first and second feature sets, wherein the third feature sets represents the user provided elements.

13. A system for conducting progressive feature evaluation to identify a feature of interest in a document, the system comprising:
-
a controller in communication with a storage device configured to receive and accessibly store a generated plurality of document images, wherein the controller is operable to; receive a document image from the storage device; identify a first pixel of the received document image having a first characteristic; define a neighborhood of pixels of the received document image, wherein the neighborhood of pixels includes one or more additional pixels having the first characteristic and being within a threshold distance of the first pixel or any of the one or more additional pixels; define an area including the defined neighborhood of pixels; identify an aspect ratio of the defined area; and compare the identified aspect ratio to one or more defined aspect ratios, wherein the one or more defined aspect ratios correspond to one or more features, and determine the feature of the one or more features corresponding to the identified aspect ratio. - View Dependent Claims (14, 15, 16, 17)

18. A computer implemented method for conducting progressive feature evaluation to identify a feature of interest in a document, the method comprising:
-
receiving, by a processor, a document image and storing the document image in a memory coupled with the processor; identifying, by the processor, a first pixel of the stored document image having a first characteristic; identifying, by the processor, a second pixel of the stored document image having the first characteristic; defining, by the processor, a first neighborhood of pixels of the stored document image, wherein the first neighborhood of pixels includes one or more additional pixels having the first characteristic and being within a threshold distance of the first pixel or any of the one or more additional pixels. defining, by the processor, a first area including the first defined neighborhood of pixels; defining, by the processor, a second neighborhood of pixels of the stored document image, wherein the second neighborhood of pixels includes one or more second additional pixels having the first characteristic and being within a threshold distance of the second pixel or any of the one or more second additional pixels; defining, by the processor, a second area including the second defined neighborhood of pixels; identifying, by the processor, on the document image, a position of the first defined area and a position of the second defined area; and determining, by the processor, a feature of the document image using the identified position of the first defined area and the identified position of the second defined area. - View Dependent Claims (19, 20)
