WebJan 8, 2013 · This information is sufficient to find the object exactly on the trainImage. For that, we can use a function from calib3d module, ie cv.findHomography (). If we pass the set of points from both the images, it will find the perspective transformation of that object. Then we can use cv.perspectiveTransform () to find the object. WebIn all methods to match the method train () is run every time before matching. Some descriptor matchers (e.g. BruteForceMatcher) have empty implementation of this method, other matchers really train their inner structures (e.g. FlannBasedMatcher trains flann::Index). So nonempty implementation of train () should check the class object state …
