      Note that this task only requires localization results (as indicated in results format in the tasks page), but the ground truth also provides the script id of each bounding box and the transcription. This extra information will be needed in Tasks 3 and 4.   
      Extra information about the training set (may be useful for researchers who focus on one or only few languages, not all of the multi-lingual set):   	
      The 10,000 images are ordered in the training set such that: each consecutive 1000 images contain text of one main language (and it may of course contain additional text from 1 or 2 other languages, all from the set of the 10 languages)
