tf.image.sobel_edges(
    image
)

image Image tensor with shape [batch_size, h, w, d] and type float32 or float64. The image(s) must be 2x2 or larger.

Tensor holding edge maps for each channel. Returns a tensor with shape [batch_size, h, w, d, 2] where the last two dimensions hold [[dy[0], dx[0]], [dy[1], dx[1]], ..., [dy[d-1], dx[d-1]]] calculated using the Sobel filter.
