| int: Gets or sets the minimum number of features the result classifier should have. | |
| max_coarse_layer_scale = property | |
| int: Gets or sets the maximum exponent of the scale factor between the coarse layer and the image. | |
| profile_delta = property | |
| int: Gets or sets the distance (in pixels) between adjacent profile points. | |
| profile_size = property | |
| int: Gets or sets the profile size which gives the number of profile points to be used for correlation around each feature. | |
