tf.nn.max_pool2d

Performs the max pooling on the input.

input A 4-D Tensor of the format specified by data_format.
ksize An int or list of ints that has length 1, 2 or 4. The size of the window for each dimension of the input tensor.
strides An int or list of ints that has length 1, 2 or 4. The stride of the sliding window for each dimension of the input tensor.
padding A string, either 'VALID' or 'SAME'. The padding algorithm. See the "returns" section of tf.nn.convolution for details.
data_format A string. 'NHWC', 'NCHW' and 'NCHW_VECT_C' are supported.
name Optional name for the operation.

A Tensor of format specified by data_format. The max pooled output tensor.
