Defined in generated file: tensorflow/python/ops/gen_array_ops.py.
Extract patches from images and put them in the "depth" output dimension.
Args:
images: ATensor. 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 ofintsthat has length>= 4. The size of the sliding window for each dimension ofimages.strides: A list ofintsthat has length>= 4. 1-D of 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 ofintsthat has length>= 4. 1-D of 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 withpatch_sizes_eff = patch_sizes + (patch_sizes - 1) * (rates - 1), followed by subsampling them spatially by a factor ofrates. This is equivalent toratein dilated (a.k.a. Atrous) convolutions.padding: Astringfrom:"SAME", "VALID". The type of padding algorithm to use.We specify the size-related attributes as:
ksizes = [1, ksize_rows, ksize_cols, 1] strides = [1, strides_rows, strides_cols, 1] rates = [1, rates_rows, rates_cols, 1]name: A name for the operation (optional).
Returns:
A Tensor. Has the same type as images.
