Description：
For training set, we've made an ample expansion. Specifically, we rotated images where its angale between ten degrees. In addition, we adjusted the pictures' brightness and constrast randomly. Finally, we got a dataset which is 40 times bigger than the original dataset. With regards to the network, we developed net which mixed ResNet, AlexNet, etc. Our team did a lot of fine-tuning on for each classical CNN, in order that they can work together. At last, we did a vote based on ResNet's and AlexNet's result to get the result.
