System and method for reconstructing an image

A method of reconstructing an image, the method comprising:

• pre-processing, by an image reconstruction device, an input image to generate a plurality of character images, wherein each of the plurality of character images corresponds to a character in the input image;
• determining, by the image reconstruction device, a local character thickness threshold value for each of the plurality of character images, wherein the local character thickness threshold value in a character image is based on a set of character pixel values in a pre-determined number of segments in the character image;
• determining, by the image reconstruction device, a global character thickness threshold value for the input image based on the local character thickness threshold value for each of the plurality of character images;
• and
• reconstructing, by the image reconstruction device, each of the plurality of character images, based on the local character thickness threshold value for each of the plurality of character images and the global character thickness threshold value, to generate a plurality of reconstructed character images.

A non-transitory computer-readable medium storing computer-executable instructions for:

• pre-processing an input image to generate a plurality of character images, wherein each of the plurality of character images corresponds to a character in the input image;
• determining a local character thickness threshold value for each of the plurality of character images, wherein the local character thickness threshold value in a character image is based on a set of character pixel values in a pre-determined number of segments in the character image;
• determining a global character thickness threshold value for the input image based on the local character thickness threshold value for each of the plurality of character images;
• and
• reconstructing each of the plurality of character images, based on the local character thickness threshold value for each of the plurality of character images and the global character thickness threshold value, to generate a plurality of reconstructed character images.
