Enum MaskResolution 

pub enum MaskResolution {
    Proto,
    Scaled {
        width: u32,
        height: u32,
    },
}

Controls the resolution and coordinate frame of masks produced by ImageProcessor::materialize_masks.

• Proto returns per-detection tiles at proto-plane resolution (e.g. 48×32 u8 for a typical COCO bbox on a 160×160 proto plane). This is the historical behavior of materialize_masks and the fastest path because no upsample runs inside HAL. Mask values are continuous sigmoid output quantized to uint8 [0, 255].
• Scaled returns per-detection tiles at caller-specified pixel resolution by upsampling the full proto plane once and cropping by bbox after sigmoid. The upsample uses bilinear interpolation with edge-clamp sampling — semantically equivalent to Ultralytics’ process_masks_retina reference. When a letterbox is also passed to materialize_masks, the inverse letterbox transform is applied during the upsample so mask pixels land in original-content coordinates (drop-in for overlay on the original image). Mask values are binary uint8 {0, 255} after thresholding sigmoid > 0.5 — interchangeable with Proto output via the same > 127 test.

Variants

Proto

Per-detection tile at proto-plane resolution (default).

Scaled

Per-detection tile at (width, height) pixel resolution in the coordinate frame determined by the letterbox parameter of ImageProcessor::materialize_masks.

Fields

width: u32

Target pixel width of the output coordinate frame.

height: u32

Target pixel height of the output coordinate frame.
