Looks like weve ran into trouble for the first time: Our detector thinks the chin is an eye too, for some reason. Faces object is just an array with small sub arrays consisting of four numbers. Now, if we try to detect blobs on that image, itll give us this: And since that was originally our eye image, we can draw the same circle on our eye image: Believe it or not, thats basically all. Well, eyes follow the same principle as face detection. But what we did so far should be enough for a basic level. Thanks. The code is written on Python3.7. Please Given a region, I can submit it to many weak classifiers, as shown above. But now, if we have a face detector previously trained, the problem becomes sightly simpler, since the eyes will be always located in the face region, reducing dramatically our search space. Retracting Acceptance Offer to Graduate School. Are you sure you want to create this branch?
