(English Abstract)
In this paper we present a computer vision based banknote recognition system for the blind intended to be used in real life scenarios. Our system is robust to cluttered backgrounds, changes in scale, rotation, illumination, partial occlusion, and a substantial range of change in 3D view point of the banknote. Our system unlike others operates fast on real-life videos obtained through a smartphone and not on single pictures. It detects the banknote by a foreground subtraction method which is robust to camera jitter. If the resultant image reaches the area and number of keypoints thresholds, its Speeded-Up Robust Features (SURF) are computed and matched against the descriptors stored in the references images descriptors database. We achieve a recognition accuracy of 94% in our 100 short real-life videos database.
