Struct EdgeDetector

Source

pub struct EdgeDetector { /* private fields */ }

Expand description

边缘检测器封装，持有预分配的 CannyWorkspace 以避免帧间堆分配。

Implementations§

Source §

impl EdgeDetector

Source

pub fn new(width: usize, height: usize) -> Result<Self, DocQuadError>

Source

pub fn detect( &mut self, buffer: &DocBuffer<'_>, ) -> Result<Vec<u8>, DocQuadError>

Source

pub fn detect_with_debug( &mut self, buffer: &DocBuffer<'_>, debug_dir: Option<&Path>, ) -> Result<Vec<u8>, DocQuadError>

执行 Canny 边缘检测，可选输出调试中间图到指定目录。

§参数

buffer：输入图像缓冲区
debug_dir：若 Some(path)，则将各阶段中间图保存到该目录
