Expand description

Image operations trait for ImageBuf method dispatch.

Provides a unified interface for applying image processing operations to structured ImageBuf instances with automatic dimension handling.

Required Methods§

Source

fn apply_conv2d( &self, kernel: &[f32], kw: usize, kh: usize, border: BorderMode, ) -> Result<ImageBuf, ImageError>

Apply 2D convolution with given kernel and border mode.

Source

fn blur(&self, sigma: f32) -> Result<ImageBuf, ImageError>

Apply Gaussian blur with given sigma.

Source

fn sobel_gradients(&self) -> Result<(ImageBuf, ImageBuf), ImageError>

Compute Sobel gradients (gx, gy).

Source

fn canny_edges( &self, sigma: f32, low: f32, high: f32, ) -> Result<ImageBuf, ImageError>

Morphological dilation with structuring element.

Source

fn apply_erode( &self, se: &[f32], sw: usize, sh: usize, ) -> Result<ImageBuf, ImageError>

Morphological erosion with structuring element.

Source

fn apply_resize( &self, new_w: usize, new_h: usize, interp: Interpolation, ) -> Result<ImageBuf, ImageError>

Resize image to new dimensions.

Source

fn to_gray(&self) -> Result<ImageBuf, ImageError>

Convert to grayscale.

Source

fn to_hsv(&self) -> Result<ImageBuf, ImageError>

Convert RGB to HSV color space.

Source

fn compute_histogram(&self, bins: usize) -> Result<Vec<u32>, ImageError>

Compute histogram with given number of bins.

Source

fn label_components(&self) -> Result<(Vec<u32>, u32), ImageError>

Label connected components in binary image.
