quality: Specify the quality that the algorithm will use. Available options are: low (fastest), medium (balanced perf and quality) and high (slowest). gridsize: size of the regular grid over the image, each cell will result in one motion vector. Use 1 for dense grid. ...
The Dense Optical Flow module estimates motion vectors between frames. This algorithm consists of multiple stages, and is performed on multiple hardware units: VIC (Video Image Compositor). NVIDIA NVENC (NVIDIA Video Encoder). PVA (Programmable Vision Accelerator). ...
安装dense flow, 博主首先尝试官方指定安装opencv3.1,再安装dense flow失败。所以选择安装opencv2.4.13。源码地址 编译opencv2.4.13 # 下载源码 wget https://github.com/opencv/opencv/archive/2.4.13.6.zip # 解压编译 unzip 2.4.13.6.zip cd opencv-2.4.13.6/ mkdir build && cd build cmake -D CMAKE_BUILD...
To this end, we propose algorithm consists of vectors obtained by applying multi-resolution analysis of motion using Haar Wavelet Packet (HWP) over time. Its computation efficiency and robustness have led HWP to gain popularity in texture analysis but their applicability in motion analysis is yet ...
