The latter unifies segmentation for all frames into a single structure, enabling the proposed framework to be simplified and end-to-end trainable.
Implicationpartial
Directly stated in abstract as key technical feature
Verificationpartial
partial
Evidencepartial
Previous studies rely on unidirectional and implicit text-trajectory alignment, which struggles with trajectory perception when faced with severe video dynamics.
Implicationpartial
Directly stated in abstract as limitation of previous approaches
