Blur Filters

impl<B: Backend> Image<B> {
    pub fn box_blur(self, kernel_size: usize) -> Result<Self>;
    pub fn gaussian_blur(self, kernel_size: usize, sigma: f64) -> Result<Self>;
    pub fn median_blur(self, kernel_size: usize) -> Result<Self>;
    pub fn bilateral_filter(&self, d: isize, sigma_color: f64, sigma_space: f64) -> Result<Self>;
    pub fn sep_filter_2d(&self, kernel_x: &[f32], kernel_y: &[f32]) -> Result<Self>;
}

Utility Filters

impl<B: Backend> Image<B> {
    pub fn filter2d(
        &self,
        kernel: &[&[f32]],
        anchor: Option<(isize, isize)>,
        delta: f32,
    ) -> Result<Self>;

    pub fn distance_transform(&self) -> Result<Self>;
    pub fn laplacian_of_gaussian(&self, sigma: f64) -> Result<Self>;
    pub fn copy_to(&self, dst: &mut Self, mask: Option<&Self>) -> Result<()>;
}

Blending

impl<B: Backend> Image<B> {
    pub fn add_weighted(&self, other: &Self, alpha: f32, beta: f32, gamma: f32) -> Result<Self>;
}

Type Conversion

impl<B: Backend> Image<B> {
    pub fn convert_scale_abs(&self, scale: f32, shift: f32) -> Result<Self>;
}
