class SlicePatches : public mindspore::dataset::TensorTransform

Note

Slice the tensor to multiple patches in horizontal and vertical directions.

Public Functions

SlicePatches(int32_t num_height = 1, int32_t num_width = 1, SliceMode slice_mode = SliceMode::kPad, uint8_t fill_value = 0)

Constructor.

Note

The usage scenerio is suitable to tensor with large height and width. The tensor will keep the same if set both num_height and num_width to 1. And the number of output tensors is equal to num_height*num_width.

Parameters

  • num_height – [in] The number of patches in vertical direction (default=1).

  • num_width – [in] The number of patches in horizontal direction (default=1).

  • slice_mode – [in] An enum for the mode of slice (default=SliceMode::kPad).

  • fill_value – [in] A value representing the pixel to fill the padding area in right and bottom border if slice_mode is kPad. Then padded tensor could be just sliced to multiple patches (default=0).

~SlicePatches() = default

Destructor.
