Abstract
An original image containing a string of text is received. The string of text contained in the original image is determined using text recognition. A first compression level applied to the original image creates a first compressed image. A string of text contained in the first compressed image is determined using text recognition. The string of text contained in the original image is compared with the string of text contained in the first compressed image. The first compression level is incremented to reach a second compression level. The second compression level applied to the original image creates a second compressed image. A string of text contained in the second compressed is determined image using text recognition. The string of text contained in the original image is compared with the string of text contained in the second compressed image. It is determined that further image compression refinement is unnecessary.
