./tools/convert_imageset_and_flow.cpp show that you load color image, but as i known, the tranditional optical flow estimation alg is based on gray scale image,why do you use color image?

Color images contain more information than gray-scale images. Most modern optical flow algorithms (e.g. Brox et al.) use color image pair. Of course, you can also use gray-scale images.

hello, I retrained the model on KITTI dataset, but the performance is not fine. So I would like to ask you the finetune learning rate and other changes about solver.prototxt. Thanks!
