Adaptive modal damping control experiment for piezoelectric structures 压电结构的自适应模态阻尼控制实验
Wavelet edge detection technology was applied to image segmentation of blasted muck - pile , in which quadric bspline wavelet and a method of adaptive thresholds edge detection for image based on wavelet transform were applied , and methods of expanding and deleting short chain were used to delete untrue edge better 摘要把小波边缘检测技术应用于爆堆图像分割处理中,采用基于最优条件下二次b样条小波和自适应模极大值的图像边缘检测算法,综合运用膨胀技术和短链删除技术,很好的去除了伪边缘。
