The LR images in TextZoom is much more challenging than synthetic LR images(BICUBIC).
We allocate our dataset into 3 part following difficulty: easy, medium and hard subset. The misalignment and ambiguity increases as the difficulty increases.
For each pair of LR-HR images, we provide the annotation of the case sensitive character string (including punctuation), the type of the bounding box, and the original focal lengths.
