Struct Interpolate2d 

pub struct Interpolate2d {
    pub output_size: Option<[usize; 2]>,
    pub scale_factor: Option<[f32; 2]>,
    pub mode: Ignored<InterpolateMode>,
}

Interpolate module for resizing tensors with shape [N, C, H, W].

This struct represents an interpolation module that can resize tensors using various interpolation methods. It provides flexibility in specifying either an output size or a scale factor for resizing, along with options for the interpolation mode.

The module can be used to upsample or downsample tensors, preserving the number of channels and batch size while adjusting the height and width dimensions.

The module can be created using the Interpolate2dConfig struct and the init method, which returns an instance of the Interpolate2d struct.

Fields

output_size: Option<[usize; 2]>

Output size of the interpolated tensor

scale_factor: Option<[f32; 2]>

Scale factor for resizing the input tensor

mode: Ignored<InterpolateMode>

Interpolation mode used for resizing

Implementations

impl Interpolate2d

pub fn forward<B>(&self, input: Tensor<B, 4>) -> Tensor<B, 4>

where B: Backend,

Performs the forward pass of the interpolation module

Arguments

• input - Input tensor with shape [N, C, H, W]

Returns

Resized tensor with shape [N, C, H’, W’], where H’ and W’ are determined by the output_size or scale_factor specified in the module configuration

Example

let input = Tensor::<Backend, 2>::random([1, 3, 64, 64], Distribution::Uniform(0.0, 1.0), &device);
let interpolate = Interpolate2dConfig::new()
    .with_output_size(Some([128, 128]))
    .init();
let output = interpolate.forward(input);
assert_eq!(output.dims(), [1, 3, 128, 128]);
