System and method for processing image for identifying alphanumeric characters present in a series
First Claim
Patent Images
1. A method for identification of alphanumeric characters present in a series in an image, the method comprising steps of:
- capturing the image comprising the series of alphanumeric characters;
processing, by a processor of a computerized device, the image for producing a set of identifiable characters out of the series of alphanumeric characters;
the processing further comprising;
computing, by the processor, a pattern for recognizing a pixel intensity distribution in the image for determining a background peak and a foreground peak;
generating, by the processor, a plurality of binarized images by selecting a plurality of dynamic threshold values between the background peak and the foreground peak;
filtering, by the processor, the generated binarized images by removing unwanted components from plurality of images to identify one or more valid characters;
identifying, by the processor, one or more candidate images by comparing the valid characters with respect to a known ground truth value;
generating, by the processor, a final candidate image by combining the candidate images such that the combination of the candidate images is dependent upon a predefined condition; and
splitting, by the processor, the final candidate image into a predefined segments and recognizing a valid alphanumeric character associated with each segment therein.

Abstract
A system and a method for identification of alphanumeric characters present in a series in an image are disclosed. The system and method captures the image and further processes it for binarization by computing a pattern of the image. The generated binarized images are then filtered for removing unwanted components. Candidate images are identified out of the filtered binarized images. All the obtained candidate images are combined to generate a final candidate image which is further segmented in order to recognize a valid alphanumeric character present in the series.
