Video mosaicing for camera-based text recognition
Miyazaki Hiromitsu, Uchida Seiichi, Hiroaki Sakoe · IEICE Technical Report; IEICE Tech. Rep. · 2005
In this paper, a mosaicing-by-recognition technique is proposed, where video mosaicing and text recog- nition are simultaneously and collaboratively optimized in a one-step manner. Specifically, multiple frames where a long text line is captured while moving a camera are optimally matched and concatenated with a guide of the text recognition framework. The optimization is performed by a DP-based algorithm and can compensates rotation, scaling, and speed fluctuation which appear in texts captured by hand-held cameras. The results of an experiment to evaluate not only the accuracy of mosaicing but also that of text recogntion indicates that the proposed technique
