1.The parameters for model inference which you can modify to investigate more models.
2.Main loop in which will read the image from canvas and do inference once.
3.Load labels from txt file and process it into an array.
4.Get blob from image as input for net, and standardize it with mean and std.
5.Fetch model file and save to emscripten file system once click the input button.
