This section demonstrates a Python implementation of Otsu's binarization to show how it actually works. If you are not interested, you can skip this. Since we are working with bimodal images, Otsu's algorithm tries to find a threshold value (t) which minimizes the weighted within-class variance given by the relation: The following are 30 code examples for showing how to use imageio.get_writer().These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.最近在用PIL合成PNG图像为GIF时，因为需要透明背景，所以就用putpixel的方法替换背景为透明，但是在合成GIF时，图像出现了重影，在网上查找了GIF的相关资料：GIF相关资料其中有对GIF帧数处理的说明，需要在GIF图像的header中设置disposal的处置方法然后我们可以查看PIL库中关于GIF的定义文件GifImagePlugin ...

Arcade is an easy-to-learn Python library for creating 2D video games. It is ideal for people learning to program, or developers that want to code a 2D game without learning a complex framework. The wavelength and the speed of the wave determine the pitch, or frequency of the sound. Wavelength, frequency, and speed are related by the equation speed = frequency * wavelength. Since sound travels at 343 meters per second at standard temperature and pressure (STP), speed is a constant. Thus, frequency is determined by speed / wavelength.

Python has some great data visualization librairies, but few can render GIFs or video animations. This post shows how to use MoviePy as a generic animation plugin for any other library. MoviePy lets you define custom animations with a function make_frame(t) , which returns the video frame corresponding to time t (in seconds):
When the figures are finished plotting, the library 'imageio' takes the .png files and loops through them with the selected interval and saves them as an animated .gif file. The Github repository for creating a Python GIF can be found here at the project's page entitled 'gifly.' You can also click on the GIF above to be taken to the project's page.
