Struct ImageProcessor 

pub struct ImageProcessor {
    pub cpu: Option<CPUProcessor>,
}

Image converter that uses available hardware acceleration or CPU as a fallback.

Fields

cpu: Option<CPUProcessor>

CPU-based image converter as a fallback. This is only None if the EDGEFIRST_DISABLE_CPU environment variable is set.

Implementations

impl ImageProcessor

pub fn new() -> Result<Self>

Creates a new ImageProcessor instance, initializing available hardware converters based on the system capabilities and environment variables.

Examples

let image = include_bytes!("../../../testdata/zidane.jpg");
let img = TensorImage::load(image, Some(RGBA), None)?;
let mut converter = ImageProcessor::new()?;
let mut dst = TensorImage::new(640, 480, RGB, None)?;
converter.convert(&img, &mut dst, Rotation::None, Flip::None, Crop::default())?;

Trait Implementations

impl Debug for ImageProcessor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl ImageProcessorTrait for ImageProcessor

fn convert( &mut self, src: &TensorImage, dst: &mut TensorImage, rotation: Rotation, flip: Flip, crop: Crop, ) -> Result<()>

Converts the source image to the destination image format and size. The image is cropped first, then flipped, then rotated

Prefer hardware accelerators when available, falling back to CPU if necessary.

fn convert_ref( &mut self, src: &TensorImage, dst: &mut TensorImageRef<'_>, rotation: Rotation, flip: Flip, crop: Crop, ) -> Result<()>

Converts the source image to a borrowed destination tensor for zero-copy preprocessing.

fn render_to_image( &mut self, dst: &mut TensorImage, detect: &[DetectBox], segmentation: &[Segmentation], ) -> Result<()>

fn set_class_colors(&mut self, colors: &[[u8; 4]]) -> Result<()>

Sets the colors used for rendering segmentation masks. Up to 17 colors can be set.
