Struct HistogramKernel 

pub struct HistogramKernel { /* private fields */ }

Histogram computation kernel

Implementations

impl HistogramKernel

pub fn new(num_bins: usize, min_value: f32, max_value: f32) -> Self

Create a new histogram kernel

Arguments

• num_bins - Number of histogram bins
• min_value - Minimum value for histogram range
• max_value - Maximum value for histogram range

pub fn default_u8() -> Self

Create a histogram with default range [0, 256) for 8-bit images

pub fn execute(&self, _device: &GpuDevice, input: &[u8]) -> Result<Vec<u32>>

Execute histogram computation (CPU fallback).

Each byte value v in input is mapped to a bin via: bin = clamp(((v - min) / (max - min)) * num_bins, 0, num_bins-1)

Arguments

• _device - GPU device (CPU fallback: unused)
• input - Input image data

Errors

Returns an error only on internal logic failures (currently infallible).

pub fn num_bins(&self) -> usize

Get the number of bins

pub fn value_range(&self) -> (f32, f32)

Get the value range

pub fn bin_width(&self) -> f32

Get bin width
