Rapid and accurate determine of blood types is very important during emergency situation before administering a blood transfusion. At present the method based on image recognition technology to quickly determine blood type has been widely used in the automated blood analyzer. In this paper, we propose a fast, accurate and robust blood group judgement method based on the image features of ABO blood...
Segmentation of ship target under complex background has important research significance in long-range ship tracking and identification, and an adaptive segmentation algorithm is proposed according to background images with different complexity. Local complexity of image is first calculated in this algorithm, and then the original image is preprocessed with different denoising methods according to...
Sea-sky-line extraction under complicated sea-sky background is an important aspect of long-range target tracking research. An algorithm based on improved local complexity is proposed according to the feature that the sky and the sea usually show up at different gray levels in sea-sky background images. Median filter is applied first to remove peak noise, and then the point set of sea-sky-line region...
A lot of instruments and devices were reported in standardized realignment of intraoral film. However, these instruments either are too cumbersome and time consuming to be used or require extensive fabrication. In this study we described a prototype of a instrument for realignment of intraoral film and evalated its reproducibility.A technique that uses this instrument was compared with a validated...
