pca face recognition python code

For objects similar to faces, you may need not less than 6,000 classifiers, each of which requires a successful match (and, of course, a fault-tolerant rate) to detect a person's face. But there is a problem: for face recognition, the algorithm starts from the upper left corner to compute a block of data, and keeps asking "Is this a

The verification code needs to be recognized when writing a program these days, because the program is written in Python and naturally intends to use Python to identify the verification code. The following describes how to implement the Program on the script home platform. If you are interested, you can refer to a popu

For python verification code recognition, there are several main methods: one is to process the image, and then use the font feature matching method. The other is to create a character matching dictionary after image processing, another type is recognition using ocr module directly. No matter what method is used, you n

Python uses KNN for verification code recognition.Preface Previously, I made an APP for campus dating. One logic is to use the user's educational administration system to confirm that the user is a college student. The basic idea is to use the user's account and password, the crawler method is used to confirm the information, but many educational administration systems have verification codes. At that time,
