Ekstrak patches
dari images
dan letakkan di dimensi keluaran "kedalaman".
Ringkasan
Argumen:
- ruang lingkup: Objek Lingkup
- gambar: Tensor 4-D dengan bentuk
[batch, in_rows, in_cols, depth]
. - ksizes: Ukuran jendela geser untuk setiap dimensi
images
. - langkahnya: Seberapa jauh pusat dari dua petak yang berurutan pada gambar. Harus:
[1, stride_rows, stride_cols, 1]
. - tarif: Harus:
[1, rate_rows, rate_cols, 1]
. Ini adalah langkah masukan, yang menentukan seberapa jauh dua sampel patch berturut-turut dimasukkan. Setara dengan mengekstraksi patch dengan patch_sizes_eff = patch_sizes + (patch_sizes - 1) * (rates - 1)
, diikuti dengan melakukan subsampling secara spasial dengan faktor rates
. Ini setara dengan rate
konvolusi yang melebar (alias Atrous). - padding: Jenis algoritma padding yang akan digunakan.
Pengembalian:
-
Output
: Tensor 4-D dengan bentuk [batch, out_rows, out_cols, ksize_rows * ksize_cols * depth]
berisi patch gambar dengan ukuran ksize_rows x ksize_cols x depth
yang divektorkan dalam dimensi "kedalaman". Catatan out_rows
dan out_cols
adalah dimensi patch keluaran.

Must be: `[1, stride_rows, stride_cols, 1]`.\n- rates: 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.\n- padding: The type of padding algorithm to use.\n\n\u003cbr /\u003e\n\nReturns:\n\n- [Output](/versions/r2.3/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): 4-D [Tensor](/versions/r2.3/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor) with shape `[batch, out_rows, out_cols, ksize_rows * ksize_cols * depth]` containing image patches with size `ksize_rows x ksize_cols x depth` vectorized in the \"depth\" dimension.
