Convolution filter operations

Implementations

impl FilterOperation

pub fn gaussian_blur( device: &GpuDevice, input: &[u8], output: &mut [u8], width: u32, height: u32, sigma: f32, ) -> Result<()>

Apply Gaussian blur

Arguments

• device - GPU device
• input - Input image buffer (packed RGBA format)
• output - Output image buffer (packed RGBA format)
• width - Image width
• height - Image height
• sigma - Blur radius (standard deviation)

Errors

Returns an error if buffer sizes are invalid or if the GPU operation fails.

pub fn sharpen( device: &GpuDevice, input: &[u8], output: &mut [u8], width: u32, height: u32, amount: f32, ) -> Result<()>

Apply sharpening filter (unsharp mask)

Arguments

• device - GPU device
• input - Input image buffer (packed RGBA format)
• output - Output image buffer (packed RGBA format)
• width - Image width
• height - Image height
• amount - Sharpening strength

Errors

Returns an error if buffer sizes are invalid or if the GPU operation fails.

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

Detect edges using Sobel operator

Arguments

• device - GPU device
• input - Input image buffer (packed RGBA format)

• width - Image width
• height - Image height

Errors

Returns an error if buffer sizes are invalid or if the GPU operation fails.

pub fn convolve( device: &GpuDevice, input: &[u8], output: &mut [u8], width: u32, height: u32, kernel: &[f32], normalize: bool, ) -> Result<()>

Apply custom convolution kernel

Arguments
