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)
