Struct ImageNormalize 

pub struct ImageNormalize {
    pub mean: [f32; 3],
    pub std: [f32; 3],
}

Per-channel normalization applied to image pixels before they enter the projector. The default ([0,1] range with no mean/std shift) is what a naive u8 / 255 does; Self::imagenet gives the (mean, std) commonly used by HF vision processors including the Gemma 4 unified reference.

Fields

mean: [f32; 3]

std: [f32; 3]

Implementations

impl ImageNormalize

pub const fn unit() -> ImageNormalize

Plain u8 / 255 — output in [0, 1].

pub const fn imagenet() -> ImageNormalize

Standard ImageNet mean/std (RGB). The Gemma 4 unified vision tower expects this shift; CLIP/SigLIP family uses [0.5; 3].

pub const fn clip() -> ImageNormalize

CLIP / OpenAI vision encoders.
