Medical system based on image processing is playing an important role in clinical medicine today. However, the checking for label on powder medicine bottle is still being done manually by pharmacists in the injection pharmacy admixture preparation process. In this article, an automated method is proposed for checking the curved label of powder medicine bottle. The proposed method mainly consists of...
The newly developed enhanced hexagonal-based search using point-oriented inner search (EHS-POIS) enormously speeds up hexagon-based search (HS). From a different perspective, an inherent correlation between distortion and spatial direction through statistical analysis is found. Based on the observed distortion distribution, a novel enhanced hexagonal-based search with direction-oriented inner search...
A critical step in fingerprint recognition is to skeletonize the fingerprint image for minutiae extraction, which is recognized as "thinning" in image processing. The speed and reliability of the thinning process are important for the whole fingerprint identification system. In this paper, to accelerate the thinning process, a fast hardware thinning algorithm is implemented on the Xilinx...
Image scaling plays an important role in digital image processing. It is widely applied in all sorts of display terminals. A new scaling method was proposed in this paper. The method combines traditional nearest neighbor and bilinear methods in a simple but effective way. The hybrid algorithm was discussed based on analysis of its idea origin. Multiple input interpolation method was put forward for...
