tf.compat.v1.extract_image_patches
Extract patches from images and put them in the "depth" output dimension.
tf.compat.v1.extract_image_patches(
    images, ksizes=None, strides=None, rates=None, padding=None, name=None,
    sizes=None
)
  | Args | |
|---|---|
images | 
      A Tensor. Must be one of the following types: bfloat16, half, float32, float64, int8, int16, int32, int64, uint8, uint16, uint32, uint64, complex64, complex128, bool. 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. |
