s6.nn.ops.layers

s6.nn.ops.layers.soft_argmax_2d(heatmap: Tensor, beta: float = 10.0) → Tensor

Apply soft-argmax on 2D heatmaps to extract keypoint coordinates in normalized [0,1).

class s6.nn.ops.layers.SoftArgmax2d(beta: float = 10.0)

Bases: Module

Soft-argmax on 2D heatmaps with a learnable beta parameter.

forward(heatmap: Tensor) → Tensor

Define the computation performed at every call.

Should be overridden by all subclasses.

Note

Although the recipe for forward pass needs to be defined within this function, one should call the Module instance afterwards instead of this since the former takes care of running the registered hooks while the latter silently ignores them.
