If you only need it for plotting a basic wordcloud, then pip install wordcloud or conda install -c conda-forge wordcloud would be sufficient. Wordcloud can be a little tricky to install. You will need this library to read in image as the mask for the wordcloud. Pillow is a wrapper for PIL - Python Imaging Library. The pillow library is a package that enables image reading. To read more about handling files with os module, this DataCamp tutorial will be helpful.įor visualization, matplotlib is a basic library that enables many other libraries to run and plot on its base including seaborn or wordcloud that you will use in this tutorial.

The Python os module is a built-in library, so you don't have to install it. It is also used in combination with Pandas library to perform data analysis. The numpy library is one of the most popular and helpful libraries that is used for handling multi-dimensional arrays and matrices. You will need to install some packages below:

Mask your wordcloud into any color pattern of your choice.

Mask your wordcloud into any shape of your choice.

Adjust color, size and number of text inside your wordcloud.

How to create a basic wordcloud from one to several text documents.In this tutorial we will use a wine review dataset taking from Wine Enthusiast website to learn: This tool will be quite handy for exploring text data and making your report more lively. For this tutorial, you will learn how to create a WordCloud of your own in Python and customize it as you see fit. Once its working with flowers.jpg, try it with poppy.jpg or times you might have seen a cloud filled with lots of words in different sizes, which represent the frequency or the importance of each word. The result is a grayscale version of the original color image. Then set the red, green, and blue values of the pixel to be that average number. This average number represents the brightness of the pixel 0.255.

The average measures how bright the pixel is 0.255įor this example, we'll write code to change the flowers.jpg image to grayscale, using the "average" strategy: for each pixel, compute the average of its red/green/blue values.

Average combines red/green/blue into one number.

More complicated brightness measures are possible, but average is simple and works fine for our purposes. The average shows how bright the pixel is, ignoring hue: 0 = totally dark, 255=totally bright, with intermediate average values corresponding to intermediate brightnesses. The average combines and summarizes the three values into one number 0.255. Looking at just red or blue or green in isolation, it's hard to tell which pixel is brightest or darkest in the above table.

Reminder: to average 3 numbers, add them up and divide by 3.

Choose a few pixels out of flowers.jpg, each in a row below.

Problem: for each pixel, how dark/light is it (ignoring hue).

How to covert a regular color image to grayscale?.

red/blue/green are made equal for each pixel. but this code gets a value from one color Usually code combines setRed() with getRed(), Image = new SimpleImage("liberty-red.jpg") So for a pixel, if red is 27, set green and blue to also be 27. This image looks quite wrong.įor this example, we'll write code to fix this image by copying the red value over to be used as the green and blue value. Here is an image of the Statue or Liberty where all of the data is in the red values, so the whole image looks red.

In fact, the original pure black/white colors fit this all-equal pattern too, just using the values 0 and 255. This works because the displays and other systems using RGB are calibrated so that the all-equal cases are on the spectrum. If a pixel were red=50 green=75 blue=50 it would be a bit greenish, but making them all equal, it's not towards any particular hue. Making all the numbers equal, like red=50 green=50 blue=50 drains any bias towards red, green, or blue. RGB values to make: dark gray, medium gray, light grayĪnswer: the RGB scale is calibrated so that when all three red/green/blue numbers of a pixel are equal, the pixel is a shade of gray.

Figure out how to make colors on the grayscale spectrum.

color images, and some code to play with that difference. In this section, we'll look at the structure of grayscale vs.
