Classifier Properties

Acceptance parameter for feature gradient angles. In ShapeFinder the angle of a feature is quantized into the range [0...255], i.e. in steps of roughly 1.41 degrees. When determining whether features extracted from an image match features stored in a classifier, the gradient's angle of the two features is compared not for strict equality, but for whether or not it falls into a certain range of differences. This acceptance window is defined by the Angular tolerance parameter. Valid values range from 0 (always match for identity only) to 16.

Comment assigned to the classifier.

Threshold for the gradient slope.

Number of features this classifier contains.

Feature window of this classifier (i.e. the bounding rectangle into which all the classifier's features fit) relative to the classifier's origin.

Name of the file from which this classifier was loaded (string.Empty if this image list was neither loaded nor saved since its construction).

Gradient type this classifier uses for feature extraction.

Native ShapeFinder2 classifier handle.

Tests if the native handle has already been disposed.

Number of layers in the classifier (and in the accumulator generated by the search function). In ShapeFinder classifiers layers may be associated with specific classes or rotation information. In ShapeFinder2 the layer count is a purely informational value.
