.. py:function:: estimate_aggd_param(block: torch.Tensor, return_sigma=False) -> Tuple[torch.Tensor, torch.Tensor, torch.Tensor]

   Estimate AGGD (Asymmetric Generalized Gaussian Distribution) parameters.
   :param block: Image block with shape (b, 1, h, w).
   :type block: Tensor

   :returns: alpha, beta_l and beta_r for the AGGD distribution
             (Estimating the parames in Equation 7 in the paper).
   :rtype: Tensor
