Implementing the Lazy Eyes app

Let's create a new folder for Lazy Eyes and, in this folder, create copies of or links to the ResizeUtils.py and WxUtils.py files from any of our previous Python projects such as the project The Living Headlights in Chapter 5, Equipping Your Car with a Rearview Camera and Hazard Detection. Alongside the copies or links, let's create a new file, LazyEyes.py. Edit it and enter the following import statements:

import collections
import numpy
import cv2
import threading
import timeit
import wx

import pyfftw.interfaces.cache
from pyfftw.interfaces.scipy_fftpack import fft
from pyfftw.interfaces.scipy_fftpack import ifft
from scipy.fftpack import fftfreq

import ResizeUtils
import WxUtils

Besides the modules that we have used in previous projects, we are now using the standard library's collections module for efficient collections and timeit module for precise timing. Also for the first time, we are using signal processing functionality from PyFFTW and SciPy.
