gnizing the sperm¡¡¥s mathematical form, the fully automatic sperm analyzer will number each sperm itself. Each sperm will get a particular code, and it will be followed up tracing its trajectory by green line to get more accurate motion parameters and statistical parameters. H. This software adopts automatic recognition mode and accurate identification mode, is the advanced technology in china which can improve the testing accuracy. A). Automatic mode: based on the best parameters to identify directly B). Accurate mode: after more than once recognizing and adjusting its parameters, if there are still have the problems like mis-recognizing or the omission of recognition , the software in accurate mode will eliminate the mis- recognized sperm and cover the omission in order to making the recognition rate reaching 100%.
