In this activity, you will create a \"luminance (grey) histogram\" for a picture # chosen by the user. A luminance histogram is created by counting how many # pixels are there for each level of luminance and then by drawing a chart (typically # a bar chart) showing \"how popular\" each luminance value was in the image. # Please check Google Images for examples. # There are many ways to approach this. Here\'s the suggested approach (feel free to # follow your own as long as yours is functionally the same or better): #
1. Create a list of 256 integers as follows: # histogramData=[0]*256 #
2. Go through each pixel of the image and at each pixel: #
2.1: Calculate the luminance \"lum\" of that pixel (i.e. the average of RGB # values). This value would be an integer between 0-255. #
2.2: Increment the value in the list at position \"lum\" by 1. #
3. The previous step will generate the data necessary for the histogram. You # must now create an empty image for the histogram. It should be 256 pixels # wide as there are only 256 unique levels. The height of the histogram should # be tall enough to fit the largest value in the histogramData list. You can # manually estimate what the height at first but later you can think about # making the height dynamic to different pictures\' histograms. #
4. Go through the histogram list and for each item, draw a line (i.e. a bar # in the bar chart) whose height corresponds to the value of the item # in the list. # The lines should start from the bottom of the image. The x coordinates of # each line will correspond to the list element\'s position. E.g. list item at # position zero will have its line drawn at x zero in the histogram.
Write a short program in Python that turns on all LEDs, one at a time, in a looping fashion. When an LED is on, it should stay on for 1 second.
Implement the Sieve of Eratosthenes and use it to find all prime numbers less than or equal to one million. Use the result to prove Goldbach's Conjecture for all even integers between four and one million, inclusive.
Write an algorithm in structured English (pseudocode) that describes the steps required to perform the task specified and reinforce topic material related to the programming work cycle, and the input, processing, output program structure.
How can you turn the turtle image into a .gif picture when using the built-in turtle for Python? If that's impossible how do you remove the line when you move the turtle around?
Write a Python program called hours.py which imports three dictionaries, and uses the data in them to calculate how many hours each person has spent in the lab.
You will write a Python program that is capable of generating a likely set of completion words given the start of a word as input to the program.
Implement functions for Insertion sort and bubble sort in python programming language and a function that calculates the function execution time.
List the things you changed and the purpose of changing it. Good reasons include making code easier to read and easier to navigate when modifying it.
What you will be implementing here is inspired by real world cases such as the Conficker work. To have any chance of defeating such a threat, you need to understand how they defend themselves.
