+Package detect implements an object detector cascade.
+
+The technique used is a degenerate tree of Haar-like classifiers, commonly
+used for face detection. It is described in
+
+	P. Viola, M. Jones.
+	Rapid Object Detection using a Boosted Cascade of Simple Features, 2001
+	IEEE Conference on Computer Vision and Pattern Recognition
+
+A Cascade can be constructed manually from a set of Classifiers in stages,
+or can be loaded from an XML file in the OpenCV format with
+
+	classifier, _, err := detect.ParseOpenCV(r)
+
+The classifier can be used to determine if a full image is detected as an
+object using Detect
+
+	if classifier.Match(m) {
+		// m is an image of a face.
+	}
+
+It is also possible to search an image for occurrences of an object
+
+	objs := classifier.Find(m)
