We need to start thinking about how to convert a set of texts into quantifiable things. The simplest method is to consider word frequency.
I will try not to use NLTK and Scikits-Learn packages. First, we will use Python to explain some basic concepts.

Therefore, I use sublime text to write a Python program.Then the whole building is actually very simple. Considering the next thing to do is scientific research, we also install Numpy,scipy,ma

1. Capturing the desired picture 2. This captures the "Firefox home" four characters, then the color of the text 3. The color consists of three parts, i.e. R G B wherein the r is represented by 00-FF (16 binary) or 0-255 numerical value. The same GB is the same thing. In this case there is a problem of deviation, which requires a deviation to cover all the colors within the deviation. 4. After the deviation will find the font
