Struct HistogramEqualizer 

pub struct HistogramEqualizer { /* private fields */ }

GPU-accelerated (CPU-fallback) histogram equalizer.

Implementations

impl HistogramEqualizer

pub fn new(config: HistogramEqualizerConfig) -> Self

Create a new equalizer with the given configuration.

pub fn default_config() -> Self

Create with default configuration (luma-only, no clip limit).

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

Equalize the histogram of an RGBA image.

• input / output – packed RGBA, 4 bytes per pixel.
• device – reserved for GPU dispatch; CPU path is used automatically.

Errors

Returns an error if dimensions are invalid or buffers are too small.

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

CPU-only variant — usable without a GPU device.

Errors

Returns an error if dimensions are invalid or buffers are too small.
