8. A computing system, comprising: a processor; and a memory including instructions that, when executed by the processor, cause the computing system to: receive an input image that includes at least one image variation; filter and segmenting the input image; select regions within the filtered and segmented input image having connected components; create a mask corresponding to the regions of connected components, the mask including bounding boxes that at least partially enclose corresponding regions of the connected components; intersect the filtered and segmented input image with the mask to produce a first output image; separately process the filtered and segmented input image corresponding to the mask to create a binary output image; separately recognize text in the first output image and in the binary output image using an optical character recognizer; and combine the separately recognized text from the first output image and from the binary output image to produce a single output.
10. The computing system of claim 8 , wherein the instructions, when executed by the processor, further cause the computing system to combine the separately recognized text from the first output image and the second output image by taking a logical OR of the first output image and the second output image.
