Abstract
Systems and methods for evaluating a quantity of text in an image determine rows in an image that include spikes, wherein determining that a row includes a spike includes determining that a difference between the value of an earlier pixel in the row and a subsequent adjacent pixel exceeds a first threshold, and determining that a difference between a value of a later pixel in the row that is within a first predetermined range of the earlier pixel and a value of a pixel subsequent to the later pixel exceeds the first threshold; determine a number of hits in the image, wherein determining a hit includes determining that a number of rows within a predetermined row range each include a spike; determine if the number of hits exceeds a second threshold; and select an image encoder based on whether or not the number of hits exceeds the threshold.
