Image Recognition Algorithm ImplementationFavorites
In the past, image processing functions were mostly for image handles. Complex image files must be operated for algorithm implementation.
However, the algorithm implementation and debugging cycle is longer than the period.
Here is just a pure setup, even the environment is not available, but what server-side js is playing, everything has become a floating cloud, let's first build an environment, enter a "hello world" page.Yes,Build Windows 7You only need to follow me step by step, and you will be OK. You do not need to know too much details. That is not what we are concerned about now. Our primary goal is to build the environment, otherwise, there will be no next step.
