Alibaba cloud OSS upload and intelligent image recognition garbage recognition

Alibaba cloud OSS object storage upload pictures and intelligent image recognition garbage recognition I believe that the majority of novice programmers, like me, want to write an intelligent image recognition, but they can't find it in Baidu or don't know what it means when they check. Next, I will contribute my own process and code of writin ...

pytorch training classifier

Training a Classifier We learned how to define the neural network, calculate the loss and update the network weight What about data? Usually, when you have to deal with images, text, audio or video, you can use a standard python package that can load data into a numpy array, and then convert the array to torch* Tensor Image: pilot, opencvAu ...

Model fine tuning technology

1, Common skills in transfer learning: fine tuning 1.1 concept Take the weights trained on the big data set as the initialization weight of the specific task (small data set), and retrain the network (modify the full connection layer output as needed); The training methods can be: 1. Fine tune all layers; 2. Fix the weights of the front l ...

BM3D algorithm semi solution with python code

1. Ideas There are some similarities between BM3D and NLM algorithms. NLM has written before: go to They all use the features of other regions of the image and the current block features to fuse into denoised image blocks. The main differences are as follows:         1. Search only within a fixed radi ...
