agethen / dense-flow Goto Github PK

Hi agethen,

I typed in the example command usage and obtained the flow_x_chk0.flow and flow_y_chk0.flow files. I noticed in the src code, "denseFlow_gpu_cv3.cc", that there are no args for "--imgFile".
Has this function been deprecated?

Thanks.

When I make, there is an error:

Hi , the problem 'can't find libopencv_core.so.3.3' has been solved。
And now when I run './denseFlow_gpu --vidFile="video.mp4" --xFlowFile="flow_x" --yFlowFile="flow_y" --imgFile="im" --bound=16 --type=2 --device_id=0 --step=10'
I got :
(DEBUG) try_init_v4l2 VIDIOC_QUERYCAP "video.mp4": Function not implemented
Unable to stop the stream: Function not implemented
Could not open video video.mp4
Processing file: video.mp4 (0 frames)

I have OpenCV 3.3.1 and CentOS 7 . And when I compiled OpenCV 3.3.1 ,I didn't install FFMPEG and other expansion pack. Is that the problem？

Here is my result when I compile OpenCV after I run 'cmake':

Can you tell me what expansion packs I need to install ?

Hi,I really want to reappear your codes.

And now I have compiled OpenCV-3.3.1.After I run 'make simple'，I got 'denseflow_gpu' in ./build and I put 'video.mp4' in it。
However,when I run './denseFlow_gpu --vidFile="video.mp4" --xFlowFile="flow_x" --yFlowFile="flow_y" --imgFile="im" --bound=16 --type=2 --device_id=0 --step=10' ,
I got './denseFlow_gpu: error while loading shared libraries: libopencv_core.so.3.3: cannot open shared object file: No such file or directory'。

I have modify your 'Makefile.config' like this :
FLAGS=-std=c++11 -Wfatal-errors
INCLUDE=-I/nfs/project/maao/codes/tools/opencv-3.3.1-install/include -Iinclude/
LIB=-L/nfs/project/maao/codes/tools/opencv-3.3.1-install/lib
OUT=build

And in the folder '/nfs/project/maao/codes/tools/opencv-3.3.1-install/lib' , I have these files:

Can you tell me why the program can't find 'libopencv_core.so.3.3' ?

Hi,

I am applying this code to a video of 164 frames and I get some full-black flow images. Is there a way to address this problem? I don't even know why it may be happening. I got the same results from the original code.
