Outline of Final Research Achievements |
In order to realize a large-scale image inspection system for preventing human error of medicine dispensing to patients at pharmacy, research on image recognition and retrieval using space-filling curves is introduced. First a linear manifold color descriptor is proposed for medicine package recognition. And then a new shapr descriptor called hyper-complex polar Fourier analysis is developed for medicine feature extraction. Finally using several space filling curves, an adaptive Hilbert scan based Bag-of-Features is proposed for image retrieval. This method is based on adaptive selection of several scanning methods like Hilbert scan, etc., and several experiments show that the proposed method performs better than other retrieval methods.
