ICDAR 2015 Challenge has three tasks. Task 1 is Text Localization. Task 3 is Word Recognition. Task 4 is End-to-end Text Spotting. Task 2 Text Segmentation is not available.

Text Localization

The four files downloaded for task 1 are

ch4_training_images.zip
ch4_training_localization_transcription_gt.zip
ch4_test_images.zip
Challenge4_Test_Task1_GT.zip

Word Recognition

The three files downloaded for task 3 are

ch4_training_word_images_gt.zip
ch4_test_word_images_gt.zip
Challenge4_Test_Task3_GT.txt

The three files are only needed for training word recognition models. Training text detection models does not require the three files.

E2E

The nine files downloaded for task 4 are the union of the four files in the text localization task (task 1) and five vocabulary files

ch4_training_vocabulary.txt
ch4_training_vocabularies_per_image.zip
ch4_test_vocabulary.txt
ch4_test_vocabularies_per_image.zip
GenericVocabulary.txt

If you download a file named Challenge4_Test_Task4_GT.zip, please note that it is the same file as Challenge4_Test_Task1_GT.zip, except for its name. In this repository, we will use Challenge4_Test_Task4_GT.zip for ICDAR2015 dataset.
