Public Static Functions Documentation

function CalculateZScale

static inline float mediapipe::LandmarkProjectionCalculator::CalculateZScale (
    const std::array< float, 16 > & matrix
) 

Landmark's Z scale is equal to a relative (to image) width of region of interest used during detection. To calculate based on matrix: * Project (0,0) (1,0) segment using matrix. * Calculate length of the projected segment.
