A Matlab wrapper for EpicFlow

epicflow's Issues

error：output too much

error: ran out of memory before sgemm

Tried this
I1_eq_path = '../I1_eq.png';
I2_eq_path = '../I2_eq.png';
flow_save_path = '../flow.flo';
f = get_epicflow(I1_eq_path, I2_eq_path, flow_save_path);

but got this error
deepmatching-static:** conv.cpp:710: void fastconv(float_image*, float_layers*, int, int, int, float, int, res_scale*): Assertion `res->res_map.pixels || !"error: ran out of memory before sgemm"' failed.

This looks like similar issue but there is no solution available yet, do you have any work around for this?

Thanks

How to complie the Epicflow code using cmake

I want to complie the Epicflow code by myself. (macOS 10.12)
but I get this error (The error is same using the original Makefile):

image.c:214:36: error: cannot convert between vector values of different size ('float' and 'v4sf' (aka '__v4sf'))

how to solve this problem?

Thanks very much!

How to use your code for optical flow computation?

Hi @suhangpro ,
Thank you for your code. I have downloaded your code and use provided test code to generate optical flow of two images. I just choose two frames of a video, but there are some errors when I run the code.
Errors display as:

What's the problem with it? I need some more operations?? Thank you~

Error while executing deepmatching-static

Hi @suhangpro I tried running your MATLAB Wrapper to get the flow fields, but am getting an error in the execution of deepmatching-static. Here's a screenshot.

using the "get_epicflow.m"

Hi
I have a question. Is the resultant optical flow can omit the camera motion?
if no, what do you suggest for omitting the effect of camera motion?

Testing collaterals for sanity checking

Hi,

Is it possible to upload testing collaterals so that we can verify that the program has been built successfully end-to-end ?

Thank you so much!
