Image transcription / OCR
Kili Technology provides an interface for image transcription or optical character recognition (OCR) to extract text information of an image document (pdf image for instance) or image.
As with image annotation, you can combine tools from segmentation and classification of the document image.
The annotation is done by selecting the class, drawing of bounding box on the area to be transcribed, and typing the text contained in the area to be transcribed.
You can also pre-process you image with an OCR, so that when you draw a bounding box, the text is automatically extracted.
