pub struct ConvolutionKernel { /* private fields */ }

Convolution kernel

Implementations

impl ConvolutionKernel

pub fn new( kernel: Vec<f32>, width: u32, height: u32, normalize: bool, ) -> Result<Self>

Create a new convolution kernel

Arguments

• kernel - Kernel weights (must be width * height in size)
• width - Kernel width (must be odd)
• height - Kernel height (must be odd)
• normalize - Whether to normalize the kernel

pub fn sobel_x() -> Self

Create a Sobel X kernel (3x3)

pub fn sobel_y() -> Self

Create a Sobel Y kernel (3x3)

pub fn laplacian() -> Self

Create a Laplacian kernel (3x3)

pub fn box_blur(size: u32) -> Result<Self>

Create a box blur kernel

pub fn sharpen() -> Self

Create a sharpening kernel

pub fn data(&self) -> &[f32]

Get the kernel data

pub fn dimensions(&self) -> (u32, u32)

Get kernel dimensions

pub fn is_normalized(&self) -> bool

Check if normalization is enabled

pub fn apply( &self, device: &GpuDevice, input: &[u8], output: &mut [u8], width: u32, height: u32, ) -> Result<()>

Apply the convolution kernel

Arguments

• device - GPU device
• input - Input image buffer
• output - Output image buffer
• width - Image width
• height - Image height

Errors

Returns an error if the operation fails.
