How do I use the Tesseract API to iterate over words?

Question

I\'m trying to learn Python in parallel with the Tesseract API. My end goal is to learn how to use the Tesseract API to be able to read a document and do some basic error ch

Answer 1

api.Recognize()
api.SetVariable("save_blob_choices","T")
ri=api.GetIterator()
level=tesserocr.RIL.WORD
boxes = api.GetComponentImages(tesserocr.RIL.TEXTLINE, True)
text_list = []
print 'Found {} textline image components.'.format(len(boxes))
i = 0
for r in tesserocr.iterate_level(ri, level):
    symbol = r.GetUTF8Text(level)
    conf = r.Confidence(level)
    bbox = r.BoundingBoxInternal(level)
    im = Image.fromarray(img[bbox[1]:bbox[3], bbox[0]:bbox[2]])
    im.save("../out/" + str(i) + ".tif")
    text_list.append(symbol + " " + str(conf) + "\n")
    i += 1

I think the function r.BoundingBoxInternal(level) will give the bounding box of the detected word.
