Expand description

Port exposing element-wise and reduction image operations.

Required Methods§

Source

fn cvt_color( &self, src: &dyn MatView, conv: ColorConversion, ) -> Result<OwnedMatView, ImageOpsError>

Convert src between color spaces per ColorConversion.

Source

fn gaussian_blur( &self, src: &dyn MatView, ksize: (u32, u32), sigma_x: f64, sigma_y: f64, ) -> Result<OwnedMatView, ImageOpsError>

Apply a Gaussian blur with the given kernel size and sigmas.

Source

fn threshold( &self, src: &dyn MatView, thresh: f64, max_val: f64, kind: ThresholdKind, ) -> Result<OwnedMatView, ImageOpsError>

Threshold a grayscale image.

Source

fn absdiff( &self, lhs: &dyn MatView, rhs: &dyn MatView, ) -> Result<OwnedMatView, ImageOpsError>

Element-wise absolute difference of two identically shaped images.

Source

fn convert_scale_abs( &self, src: &dyn MatView, scale: f64, offset: f64, ) -> Result<OwnedMatView, ImageOpsError>

Element-wise saturate_u8(|src * scale + offset|).

Source

fn min_max_loc(&self, src: &dyn MatView) -> Result<MinMaxResult, ImageOpsError>

Locate the minimum and maximum pixel values and their first positions.

Source

fn count_non_zero(&self, src: &dyn MatView) -> Result<u64, ImageOpsError>

Count non-zero pixels in a grayscale image.

Source

fn resize( &self, src: &dyn MatView, new_width: u32, new_height: u32, ) -> Result<OwnedMatView, ImageOpsError>

Resize src to the given dimensions.
