Really cool, the test you perform !

Are the images you post the real size one ?

I can work to drastically improve the quality. The code I made is only for fast assessment. I don't really use variational refinement and don't stop at the last scale.

So there is room for improvement ...

Yes, my second question was for this case: the optical flow searches for changes in 2D, but sometimes it might find vertical component if the grayscale image had not enough information to decide (uniform zone, occlusion...). That's why I asked if we can constrain it.

No, you can't constrain it. I ...

Did you have a chance to play with it on Raspberry Pi?


Yes of course ! For know I use it in order to register 2 images in mechanics (we call it Digital Image Correlation (DIC)). Once the flow is computed, we project it on projective tranformation in order to drive an experimental tensile test ...

On a simple stereo system, the stereoBM juste compute a block matching and take the horizontal displacement field find for each BM.

The code is old and not optimal. There is so much more on OpenCV !
Starting with version 4.x, you can use DISFlow, which is really performant !

here the process to ...
