Struct BlockMasking 

pub struct BlockMasking {
    pub num_targets: usize,
    pub target_scale: (f64, f64),
    pub target_aspect_ratio: (f64, f64),
}

Block masking for images (I-JEPA style).

Masks one or more contiguous rectangular blocks as targets, with the remaining patches as context. This forces the model to predict large semantic regions from partial observations.

Fields

num_targets: usize

Number of target blocks to mask.

target_scale: (f64, f64)

Target block scale range as fraction of total patches: (min, max).

target_aspect_ratio: (f64, f64)

Target block aspect ratio range: (min, max).
