If it's XML, it IS just a text file, even if it contains the names of image files on your file system. So, the creation of an XML file is trivial, it's just a string. Figuring out how to get the data you need is the hard bit. For training a boosted cascade of weak classifiers we need a set of positive samples (containing actual objects you want to detect) and a set of negative images (containing everything you do not want to detect). The set of negative samples must be prepared manually, whereas set of positive samples is created … Ver mais Working with a boosted cascade of weak classifiers includes two major stages: the training and the detection stage.
