Struct EdgeFilter 

pub struct EdgeFilter {
    pub level: u8,
    pub limit: u8,
    pub threshold: u8,
    pub hev_threshold: u8,
    pub filter_size: u8,
}

Configuration for a single edge filter.

Fields

level: u8

Filter level (0-63).

limit: u8

Limit value.

threshold: u8

Threshold for flat detection.

hev_threshold: u8

High edge variance threshold.

filter_size: u8

Filter size (4, 8, or 14 taps).

Implementations

impl EdgeFilter

pub fn new(level: u8, sharpness: u8) -> Self

Create a new edge filter.

pub const fn should_filter(&self) -> bool

Check if filtering should be applied.

pub fn is_flat(&self, p: &[i16], q: &[i16]) -> bool

Check if this is a flat region (use wide filter).

pub fn is_flat2(&self, p: &[i16], q: &[i16]) -> bool

Check if this is an extra-flat region (use widest filter).

pub fn has_hev(&self, p1: i16, p0: i16, q0: i16, q1: i16) -> bool

Check for high edge variance.
