create

public static LBPHFaceRecognizer create(int radius,
                                        int neighbors,
                                        int grid_x,
                                        int grid_y,
                                        double threshold)

Parameters:

radius - The radius used for building the Circular Local Binary Pattern. The greater the radius, the smoother the image but more spatial information you can get.

neighbors - The number of sample points to build a Circular Local Binary Pattern from. An appropriate value is to use 8 sample points. Keep in mind: the more sample points you include, the higher the computational cost.

grid_x - The number of cells in the horizontal direction, 8 is a common value used in publications. The more cells, the finer the grid, the higher the dimensionality of the resulting feature vector.

grid_y - The number of cells in the vertical direction, 8 is a common value used in publications. The more cells, the finer the grid, the higher the dimensionality of the resulting feature vector.

threshold - The threshold applied in the prediction. If the distance to the nearest neighbor is larger than the threshold, this method returns -1. ### Notes:

• The Circular Local Binary Patterns (used in training and prediction) expect the data given as grayscale images, use cvtColor to convert between the color spaces.
• This model supports updating.

### Model internal data:

• radius see LBPHFaceRecognizer::create.
• neighbors see LBPHFaceRecognizer::create.
• grid_x see LLBPHFaceRecognizer::create.
• grid_y see LBPHFaceRecognizer::create.
• threshold see LBPHFaceRecognizer::create.
• histograms Local Binary Patterns Histograms calculated from the given training data (empty if none was given).
• labels Labels corresponding to the calculated Local Binary Patterns Histograms.
