Opencv分水岭算法——watershed自动图像分割用法 OpenCV距离变换distanceTransform应用 图像分割作为图像识别的基础,在图像处理中占有重要地位,通常需要在进行图像分割算法前找到轮廓或分割线,因此传统的分割算法主要集中在边缘检测.阈值处理等. 分水岭算法 分水岭算法是一种图像区域分割法,在分割的过程中,它会把跟临近像素间的相似性作为重要的参考依据,从而将在空间位置上相近并且灰度值相近的像素点互相连接起来构成一个封闭的轮廓,封闭性是分水岭算法的一个重要特征.其他图像分…

利用NVIDIA-NGC中的MATLAB容器加速语义分割 Speeding Up Semantic Segmentation Using MATLAB Container from NVIDIA NGC 使用单一GPU训练深度学习模式的时代已经一去不复返了.对于计算密集型算法(如语义分割),单个GPU可能需要几天时间来优化模型.但多GPU硬件很贵.不会再有了:NVIDIA的云上多GPU硬件实例,比如AWS P3,只允许你支付你使用的东西.云实例允许您利用支持Tensor核心的最新一代硬件,以适度…

1. 从细菌的趋化性谈起 0x1:物质化学浓度梯度 类似于概率分布中概率密度的概念.在溶液中存在不同的浓度区域. 如放一颗糖在水盆里,糖慢慢溶于水,糖附近的水含糖量比远离糖的水含糖量要高,也就是糖附近的水糖的浓度高,离糖越远的水糖的浓度越低. 这种浓度的渐减(反方向就是渐增)叫做浓度梯度.可以用单位距离内浓度的变化值来表示.同样,温度.电场强度.磁场强度.重力场.都有梯度的. 化学溶液的浓度梯度的概念和概率分布的梯度类似,都代表了值下降的方向. 0x2:趋化性细菌的运动方式 细菌趋化性是指有运动…
