Class Documentation

class Resize : public mindspore::ops::BaseOperator

Resize defined the Resize operator prototype of lite.

Public Functions

inline Resize()

Constructor.

void Init(const Format format, const ResizeMethod method, const int64_t new_height, const int64_t new_width, const bool preserve_aspect_ratio, const CoordinateTransformMode coordinate_transform_mode, const float cubic_coeff, const int64_t exclude_outside, const float extrapolation_value, const NearestMode nearest_mode)

Method to init the op’s attributes.

Parameters

• format – [in] Define the format of the input, which only support NHWC on lite.

• method – [in] Define the mode of resizing.

• new_height – [in] Define the height of the output.

• new_width – [in] Define the width of the output.

• preserve_aspect_ratio – [in] Define a boolean to indicate keep the aspect radio with the input. Default is false.

• coordinate_transform_mode – [in] Define the rule to map coordinate.

• cubic_coeff – [in] Define a coefficient only used in cubic interpolation.

• exclude_outside – [in] Define a value to indicate whether to set the outside of the sampling area as 0. If the value is 1, the outside area will be set as 0. Default is 0.

• extrapolation_value – [in] Define a value that will be used to fill the outside of original area if possible.

• nearest_mode – [in] Define the rule how to get nearest pixel.
