8. The computer-implemented method of claim 5 , wherein the at least one connected pixel region is identified using a one-dimensional maximally stable extremal region (MSER) algorithm.
5. A computer-implemented method, comprising: under the control of one or more computer systems configured with executable instructions, identifying at least one connected pixel region indicative of text by scanning each of a plurality of rows of at least a portion of an image to locate at least one transition between pixel values and bypassing the scanning for pixel regions determined to be unlikely to contain text, such that the image includes at least one region not identified by scanning; defining at least one first text region including a number of rows containing the at least one connected pixel region; defining at least one first padded text region including a predetermined number of rows adjacent the number of rows containing the at least one connected pixel region; generating a first text mask, wherein generating the first text mask comprises identifying regions that are determined not to contain text, and printing the at least one first text region while omitting the regions that are determined not to contain text; identifying the at least one connected pixel region indicative of text by scanning each of a plurality of columns of at least a portion of the image; eliminating false positive text indications in the plurality of columns by evaluating a stable pixel-to-length ratio associated with the plurality of columns; defining at least one second text region including a number of columns containing the at least one connected pixel region; defining at least one second padded text region including a predetermined number of columns adjacent the number of columns containing the at least one connected pixel region; and generating a second text mask of a combination of the at least one defined second text region and the at least one defined second padded text region to generate a consensus string of text.
