A study was conducted to evaluate the effects of meat and bone meal (MBM) and poultry by-product meal (PBM) as the replacement of fishmeal in the diets on the growth performance, survival and apparent digestibility coefficient (ADC) of Japanese flounder (Paralichthys olivaceus). The experimental diets included 0%, 20%, 40%, 60% and 80% MBM or PBM replacement of total fishmeal respectively. All diets were iso-nitrogenous and isocaloric. The results showed that there are no significant differences (P>0.05) in growth performance among the treatments fed with 0%-60% MBM replacement of fishmeal, while the percent weight gain (WG,%), body length gain (BLG, %) and ADC significantly decrease when fishmeal is replaced by 80% MBM. The result showed also that there are no significant differences (P>0.05) in growth performance and ADC among all treatments fed with the diets with 0%-80% replacements of fishmeal with PBM.

在使用圆型人工标志的计算机视觉检测中,人工标志的识别率和中心定位精度直接影响到检测的整体精度。传统的中心定位算法对人工标志识别率低、中心定位精度差,已不能满足精密检测的要求。文中采用Canny算子对带有圆形人工标志的数字图像进行边缘分割,通过模式识别方法、最小二乘拟合方法计算人工标志中心。该方法解决了标志识别率低的问题,提高了标志图像中心定位精度。其精度可达到亚像素级,能够满足高精度计算机视觉测量
