Optical Flow Estimation using a Spatial Pyramid Network   spynet  本文将经典的 spatial-pyramid formulation 和 deep learning 的方法相结合,以一种 coarse to fine approach,进行光流的计算.This estiamates large motions in a coarse to fine approach by warping one image of a pair…

光流分为稠密光流和稀疏光流 光流(optic flow)是什么呢?名字很专业,感觉很陌生,但本质上,我们是最熟悉不过的了.因为这种视觉现象我们每天都在经历.从本质上说,光流就是你在这个运动着的世界里感觉到的明显的视觉运动(呵呵,相对论,没有绝对的静止,也没有绝对的运动).例如,当你坐在火车上,然后往窗外看.你可以看到树.地面.建筑等等,他们都在往后退.这个运动就是光流.而且,我们都会发现,他们的运动速度居然不一样?这就给我们提供了一个挺有意思的信息:通过不同目标的运动速度判断它们与我们的距离.一…

光流适用在连续的图像系列(视频流)中,描述本身或画面目标的运动状态:在目标跟踪.运动分析.甚至slam中都有广泛应用. opencv里就有不少光流算法,其中很经典也是当前被调用最多的的Lucas-Kanade算法:参看 calcOpticalFlowPyrLK(...) 2006年,Edward Rosten在各种慢速角点检测中给出了一种快速角点检测方案,取名FAST;后续也有相关改进. http://www.edwardrosten.com/work/fast.html http://www6…

Abstract 在图像中简历稠密匹配是很重要的任务, 包括 几何匹配,光流,语义匹配. 但是这些应用有很大的挑战: 大的平移, 像素精度, 外观变化: 当前是用特定的网络架构来解决一个单一问题. 我们提出了一个 universal 网络框架,我们获得了高精度和鲁棒性,对于大的平移,通过全局和局部相关层. 我们提出的GLU-Net是SOTA的. 1. Introduction 在几何匹配任务中[18],有相同场景的不同视角. 光流[4,20]目标是估计准确的像素级别的位移. 在语义匹配任务中[1…

Video Frame Synthesis using Deep Voxel Flow 论文笔记 arXiv 摘要:本文解决了模拟新的视频帧的问题,要么是现有视频帧之间的插值,要么是紧跟着他们的探索.这个问题是非常具有挑战性的,因为,视频的外观和运动是非常复杂的.传统 optical-flow-based solutions 当 flow estimation 失败的时候,就变得非常困难:而最新的基于神经网络的方法直接预测像素值,经常产生模糊的结果. 于是,在此motivation的基础上,作者…
