Identity

class Identity<T> : Transform<T, T> (source)

An identity transform that returns its input unchanged.

This transform is useful as a starting point for building pipelines and as a no-op placeholder when a transform is required but no actual transformation is needed.

Example:

// Start a pipeline with identity
val pipeline = pipeline<Image>()
    .resize(224, 224)
    .toTensor()
    .normalize(mean, std)

Parameters

The type that passes through unchanged

Constructors
