  Object-centric learning aims to break down complex visual scenes into more
manageable object representations, enhancing the understanding and reasoning
abilities of machine learning systems toward the physical world. Recently,
slot-based video models have demonstrated remarkable proficiency in segmenting
and tracking objects, but they overlook the importance of the effective
reasoning module. In the real world, reasoning and predictive abilities play a
crucial role in human perception and object tracking; in particular, these
abilities are closely related to human intuitive physics. Inspired by this, we
designed a novel reasoning module called the Slot-based Time-Space Transformer
with Memory buffer (STATM) to enhance the model's perception ability in complex
scenes. The memory buffer primarily serves as storage for slot information from
upstream modules, the Slot-based Time-Space Transformer makes predictions
through slot-based spatiotemporal attention computations and fusion. Our
experiment results on various datasets show that STATM can significantly
enhance object-centric learning capabilities of slot-based video models.
