tf.image.extract_image_patches

Extract patches from images and put them in the "depth" output dimension.

Args
images A Tensor. Must be one of the following types: float32, float64, int32, uint8, int16, int8, int64, bfloat16, uint16, half, uint32, uint64. 4-D Tensor with shape [batch, in_rows, in_cols, depth].
ksizes A list of ints that has length >= 4. The size of the sliding window for each dimension of images.
strides A list of ints that has length >= 4. How far the centers of two consecutive patches are in the images. Must be: [1, stride_rows, stride_cols, 1].
rates A list of ints that has length >= 4. Must be: [1, rate_rows, rate_cols, 1]. This is the input stride, specifying how far two consecutive patch samples are in the input. Equivalent to extracting patches with patch_sizes_eff = patch_sizes + (patch_sizes - 1) * (rates - 1), followed by subsampling them spatially by a factor of rates. This is equivalent to rate in dilated (a.k.a. Atrous) convolutions.
padding A string from: "SAME", "VALID". The type of padding algorithm to use.
name A name for the operation (optional).
Returns
A Tensor. Has the same type as images.
