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 use8
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.
