edge to 256 D to get B, and then in the center of B take 256*256 square picture to get C, and then randomly extract 224*224 on C as a training sample, and then in the combination of image level inverse increase the sample to achieve data gain. This gain method is 2048 times times the sample increase, allowing us to run a larger network.(2) Adjust the RGB valueThe specific idea is: To do PCA analysis of three channel, get the main component, make some

1 Introduction Remember when I first contacted RoboCup 2 years ago, I heard from my seniors that Ann (artificial neural network), this thing can be magical, he can learn to do some problems well enough to deal with. Just like us, we can learn new knowledge by studying. But for 2 years, I've always wanted to learn about Ann, but I haven't been successful. The main reason for this is that the introduction o
