Raw images (photographs) of urban text scenes for camera-based Thai text recognition



Raw image collection of city scenes in Thailand with text content. Text is photographed from different angles. Also morning and evening photographs were taken in order to capture different lighting conditions. The material, 309 images, was photographed in 2013 by
Bowornrat Sriman and volunteers.

Example EXIF:
