Struct BlockMaskStats 

pub struct BlockMaskStats {
    pub mean_luma: f32,
    pub luma_variance: f32,
    pub motion_sad: f32,
    pub edge_energy: f32,
    pub block_area: u32,
}

Per-block statistics gathered during analysis (before encoding).

Fields

mean_luma: f32

Mean luma value of the block (0–255).

luma_variance: f32

Spatial variance of luma values (proxy for texture energy).

motion_sad: f32

Sum of absolute differences from motion estimation (temporal activity).

edge_energy: f32

Edge energy (e.g. Sobel gradient magnitude sum over the block).

block_area: u32

Number of pixels in the block.

Implementations

impl BlockMaskStats

pub fn from_luma_block(pixels: &[u8]) -> Self

Create stats from a raw luma block slice.

pixels should be a row-major luma block (e.g. 8×8 = 64 elements, 0–255).

Trait Implementations

impl Clone for BlockMaskStats

fn clone(&self) -> BlockMaskStats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlockMaskStats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BlockMaskStats

fn default() -> BlockMaskStats

Returns the “default value” for a type.
