9. 9 Research Topics (5/7) User-Driven Visualization

10. 10 Research Topics (6/7) Letter Recognition Color (black, white) Font and Size (small, big, specific, …) Background (almost empty, riched graphics) The letter type is a precious information to index the images Problematics To define an approach which: 1.deals with the color detection and the letter segentation 2.works without any previous knowledge (ie. one image one letter model)
