A screen image compression technology based on sub - blocking with dynamic threshold 基于动态阈值分块算法的屏幕图象压缩技术
The dynamic threshold algorithm is based on a fact that measurements at the chosen channels are in different scopes between the different observation objectives ( here as earth surface and cloud ) 双通道动态阈值法的依据是,在可见光云图和红外云图上,云和地物的值域是不同的。
The first step is construct the gaussian model for skin color under ycbcr and get the likely region of face , then skin color segmentation is carry out with the method of dynamic threshold optimizing 在ycbcr色彩空间中建立肤色分布的高斯模型,得到肤色概率似然图像,在最佳动态阈值选取算法下完成肤色区域的分割。
In this paper , wavelength assignment in wdm optical networks with dynamic traffic is studied and a fair priority based dynamic threshold algorithm for wavelength assignment without wavelength conversion proposed 摘要文章研究了波分复用( wdm )光网络中动态业务下的波长分配问题,在无波长转换器的条件下,提出了一种加入了公平性考虑的动态门限算法。
In allusion to the working characteristics and technical difficulties of 155mb / s burst mode receiver , we have put forward to the quick synchronization of inpouring phase locked loops ( pll ) . for receiving burst signal , we introduce the scheme of dc coupling and dynamic threshold decision 针对155mb s突发式收发模块的工作特点和技术难点,我们提出了注入锁相环法的快速同步技术;对于突发式信号的接收,我们采用了直流耦合和动态阈值判决的技术方案。
The values of r subtracted by g of the given citrus , leaves , or branches are very similar , but the values of g subtracted by b or r subtracted by b of citrus are different from that of leaves and branches . a rule for segmenting citrus from background was put forward that the pixel belongs to citrus if the value of r subtracted by b larger than the threshold value ( t ) , which was developed by dynamic threshold segmentation method , otherwise the pixel belongs to background 研究发现水果、树叶、树枝三者间的r与g的对应坐标值基本上分布在45对角线上;树叶、树枝的g与b和r与b的对应坐标值分布在或接近于45对角线上,而水果的g与b和r与b的对应坐标值偏离45对角线,分布在45对角线下方,且果实的r - b的平均差值比g - b的平均差值要大。
