Struct PsychoVisualModel 

pub struct PsychoVisualModel { /* private fields */ }

Psycho-visual masking model that computes per-block QP deltas.

Implementations

impl PsychoVisualModel

pub fn new(cfg: PsychoVisualConfig) -> Self

Create a new masking model with the given configuration.

pub fn default_model() -> Self

Create a masking model with default configuration.

pub fn compute_qp_delta(&self, stats: &BlockMaskStats) -> i32

Compute a QP delta for a single block.

Positive values allow higher QP (more compression); negative values force lower QP (higher quality).

The block statistics should be gathered before calling this function.

pub fn compute_frame_qp_map( &self, luma_plane: &[u8], width: usize, height: usize, motion_sad_map: Option<&[f32]>, ) -> Vec<i32>

Build a QP delta map for an entire frame.

luma_plane is the raw luma data (row-major, 8-bit), width and height are the frame dimensions. Blocks are 8×8 pixels. The returned vector has one entry per block in raster-scan order.

pub fn config(&self) -> &PsychoVisualConfig

Return the current configuration.

Trait Implementations

impl Clone for PsychoVisualModel

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

Performs copy-assignment from source.

impl Debug for PsychoVisualModel

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

Formats the value using the given formatter.
