pixelator 1.0.0

Pixelate images to a specified size and color palette for AI/ML and various other purposes

Pixelator

A simple python package to pixelate images given a color palette

Features

• Users can:
  1. Load in array data, image files or capture directly from a camera
  2. Pixelate images to a specific color palette and image resolution
  3. Access pixelated array data or write it back to an image file

Setup

Make sure you have Python 3.6.x (or higher). You can download it here.

Installation

pip install pixelator

Getting Started

Import the pixelator into your project

from pixelator import Pixelator

Some important notes:

• All data is stored and processed as BGR (to match open cv2)
  • EG: Provided pallettes should be in BGR

Examples

Load from a file:

from pixelator import Pixelator
# Use the input filename provided
image = Pixelator(filename='./images/input.jpg')
# Pixelate the image to a 28x28 black and white array
pixelated_image = image.pixelate(
    width=28,
    height=28,
    palette=[[0,0,0],[255,255,255]]
)
# Write to `output.png` scaled up to a 500x500 image (to be easily viewed)
pixelated_image.write(filename='./images/output_test_1.jpg', width=300, height=300)

Input:

Output:

Capture from a webcam:

from pixelator import Pixelator
# Capture from a webcam since no data or filename is provided
image = Pixelator()

# Pixelate the image to a 28x28 black and white array
pixelated_image = image.pixelate(
    width=64,
    height=64,
    palette=[[0,0,0],[80,80,80],[160,160,160],[200,200,200],[255,255,255]]
)
# Write to `output.png` scaled up to a 500x500 image (to be easily viewed)
pixelated_image.write(filename='./images/output_test_3.jpg', width=300, height=300)

Access Pixelator Data:

from pixelator import Pixelator
# Use the input filename provided
image = Pixelator(filename='./images/input.jpg')
# Pixelate the image to a 28x28 black and white array
pixelated_image = image.pixelate(
    width=28,
    height=28,
    palette=[[0,0,0],[255,255,255]]
)
# Show pixelated image data
print(pixelated_image.data)
