2D Image to Patch Embedding

r"""Blurs an image using the box filter. The function smooths an image using the kernel: .. math:: K = \frac{1}{\text{kernel_size}_x

Define GAN loss. Args: gan_type (str): Support 'vanilla', 'lsgan', 'wgan', 'hinge'. real_label_val (float): The value for real la

r"""Creates an operator that returns a tensor using a Laplacian filter. The operator smooths the given tensor with a laplacian kernel by convolvi

r"""Creates a criterion that measures the Structural Similarity (SSIM) index between each element in the input `x` and target `y`. The index

r"""Creates a criterion that calculates the PSNR between 2 images. Given an m x n image, .. math:: \text{MSE}(I,T) = \frac{1}{m\,n}\sum_{i=0}^
