imagezmq: Transporting OpenCV images

Introduction

imagezmq is a set of Python classes that transport OpenCV images from one computer to another using PyZMQ messaging. For example, here is a screen on a Mac computer showing simultaneous video streams from 8 Raspberry Pi cameras:

# zmqimage.py -- classes to send, receive and display cv2 images via zmq
#     based on serialization in pyzmq docs and pyzmq/examples/serialization

'''
PURPOSE:
    These classes allow a headless (no display) computer running OpenCV code
    to display OpenCV images on another computer with a display.
    For example, a headless Raspberry Pi with no display can run OpenCV code
    and can display OpenCV images on a Mac with a display.

Basic hookup

As I plan to make a custom breakout board I wanted to solder as few connections as possible. I was able to boot the device, with UART (out at least) soldering the following.

PIN	NAME
0	GND
1	3V3
2	EN

    if (!options.rel) throw new Error('Mixin: cascade delete - no relation specified');

    var async = require('async');
    
    var beforeDelete = options.before || function(inst, next) {
        process.nextTick(function() { next(null, true); });
    };
