This article is about how to achieve video character painting animation gadget based on Python, the editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it.

Introduction

Let's bring you something fun today. I'm sure you'll like it!

Do you all know this one?

Yes, even character animation, have you seen it in that corner before, but you haven't tried it yourself yet.

The editor gives you a try first, so how to turn the video animation into character painting? Today I'm going to teach you how to convert. It's very simple. I'm going to teach you how to make it today.

This tool can be converted with one click!

Text 1. Preparation

1) if you have material, you can find a short video by yourself.

2) Environmental installation

The environment used in this paper is as follows: Python3, Pycharm, numpy, cv2 and some self-contained modules.

Module installation:

The second name and principle introduction of pip install-I https://pypi.douban.com/simple/ + module

1) the video can be converted into a picture frame by frame, which can be realized by using OpenCV.

2) * * convert each picture into a character painting. The principle is to determine what character to use for each pixel according to the pixel value of the picture.

3) just play the character painting in order.
