Function Documentation

◆ createShapeRelativeEncoding()

void Digikam::RedEye::createShapeRelativeEncoding ( const std::vector< float > &  shape,
const std::vector< std::vector< float > > &  pixel_coordinates,
std::vector< unsigned long > &  anchor_idx,
std::vector< std::vector< float > > &  deltas 
)

requires

  • shape.size()%2 == 0
  • shape.size() > 0 ensures
  • #anchor_idx.size() == pixel_coordinates.size()
  • #deltas.size() == pixel_coordinates.size()
  • for all valid i:
  • pixel_coordinates[i] == location(shape,#anchor_idx[i]) + #deltas[i]

References location(), and nearestShapePoint().

◆ extractFeaturePixelValues()

void Digikam::RedEye::extractFeaturePixelValues ( const cv::Mat &  img_,
const cv::Rect &  rect,
const std::vector< float > &  current_shape,
const std::vector< float > &  reference_shape,
const std::vector< unsigned long > &  reference_pixel_anchor_idx,
const std::vector< std::vector< float > > &  reference_pixel_deltas,
std::vector< float > &  feature_pixel_values 
)

requires

  • image_type == an image object that implements the interface defined in dlib/image_processing/generic_image.h
  • reference_pixel_anchor_idx.size() == reference_pixel_deltas.size()
  • current_shape.size() == reference_shape.size()
  • reference_shape.size()%2 == 0
  • max(mat(reference_pixel_anchor_idx)) < reference_shape.size()/2 ensures
  • #feature_pixel_values.size() == reference_pixel_deltas.size()
  • for all valid i:
    • #feature_pixel_values[i] == the value of the pixel in img_ that corresponds to the pixel identified by reference_pixel_anchor_idx[i] and reference_pixel_deltas[i] when the pixel is located relative to current_shape rather than reference_shape.
