What the difference between Standard TAPIR and Online TAPIR ?

Is the former model offline track ?

Right, Standard TAPIR conduct temporal convolution on all frames (including future frames) to predict point location at every frame. While Online TAPIR replaces the temporal convolutions with similarly-shaped causal convolutions, such that the activation of each unit at time t depends only on the activations from times ≤ t.
