Struct PlateConfig 

pub struct PlateConfig {
    pub max_plate_slots: usize,
    pub alphabet: String,
    pub pad_char: char,
    pub img_height: u32,
    pub img_width: u32,
    pub keep_aspect_ratio: bool,
    pub interpolation: ImageInterpolation,
    pub image_color_mode: ImageColorMode,
    pub padding_color: PaddingColor,
    pub plate_regions: Option<Vec<String>>,
}

Inference configuration for a plate-recognition model, read from a YAML file.

Fields

max_plate_slots: usize

Maximum number of character slots predicted by the model.

alphabet: String

Full alphabet used by the model (one character per class).

pad_char: char

Padding character appended to plates shorter than max_plate_slots.

img_height: u32

Image height the model expects.

img_width: u32

Image width the model expects.

keep_aspect_ratio: bool

Whether to preserve aspect ratio via letter-box padding.

interpolation: ImageInterpolation

Interpolation method used when resizing.

image_color_mode: ImageColorMode

Colour mode: grayscale (1-channel) or rgb (3-channel).

padding_color: PaddingColor

Padding colour used when keep_aspect_ratio is true.

plate_regions: Option<Vec<String>>

Optional list of region / country labels the model can predict.

Implementations

impl PlateConfig

pub fn from_yaml(path: impl AsRef<Path>) -> Result<Self>

pub fn num_channels(&self) -> u32

Number of colour channels (1 for grayscale, 3 for RGB).

pub fn has_region_recognition(&self) -> bool

true if the model includes a region-recognition head.

pub fn pad_idx(&self) -> usize

Index of pad_char in the alphabet.
