The length of Flownet2' s result is not equal to the length of input images, how to solve this

[lonelyqian]

The length of flownet2 result for a img set is len(img_set) - 1.
I wonder how to get the optical flow for the last frame.
Could you please provide the VCOD train and test dataset?

During testing, I exclude the last frame, following the approach of some VSOD methods such as MBNM , FSNet , and UFO, which rely on optical flow. As VSCode serves as the unified model, we strive to maintain consistent settings between VSOD and VCOD. Additionally, I believe that the last frame is not crucial for VSOD and VCOD tasks, as the MATLAB evaluation tool disregards both the first and last frames during evaluation. When comparing our results with SOTA methods, we also exclude the last frame to ensure fair comparisons.

If you need optical flow information for the last frame, consider rearranging the sequence so that the last frame precedes the second-to-last frame.

The training and testing datasets can be found here: https://pan.baidu.com/s/1x4DssOItYypR1Erg6L3Sdw (pin: xgtj)
