imagenie 1.3.0

A python package to support essential trasformations on image datasets

ImaGenie

imagenie is a Python package for image augmentation and modification, providing a variety of functions to manipulate images for machine learning, computer vision, or creative purposes. Whether you need to flip, scale, convert to grayscale, or blur images, imagenie is your one-stop solution for fast and efficient image manipulation.

Features

• Flipping: flip(image, direction=0) Flips the input image either horizontally or vertically. Useful for augmenting datasets by introducing mirror-image variations. 0 = horizontal flip, 1 = vertical flip

• Scaling: scale(image, N) Resizes the input image by a given scale factor N. This is crucial for normalizing or creating variations in image resolution.

• Blurring: blur(image, stdev=1.0) Applies a Gaussian blur effect to the image. Helps simulate real-world noise or reduce sharpness for specific use cases.

• Grayscaling: grayscale(image) Converts the image to grayscale. Ideal for models that only require intensity information, excluding color features.

• Augmenting with a sequence of operations: augment(images, operations) Applies a sequence of user-defined augmentation operations to a list of images. Useful for image generating images for computer vision tasks.

Installation

To install from pypi:

$ pip install imagenie

To build from the github repo follow the following steps: Clone the repository using the following command :

$ git clone https://github.com/UBC-MDS/ImaGenie.git

then navigate to the repository by running the following command

$ cd ImaGenie

Then run the following command:

$ poetry install

Running Test Suite

In the package directory run the following command to run the test suit for this package:

$ pytest

Usage

A few exampls to get you sarted with imagenie:

1. Import the functions from the package

from imagenie.flip import flip
from imagenie.scale import scale
from imagenie.blur import blur
from imagenie.grayscale import grayscale
from imagenie.augment import augment

2. Load the images as Numpy arrays

import matplotlib.pyplot as plt
image = plt.imread(IMAGE_PATH)
image2 = plt.imread(IMAGE_PATH)

3. Leverage imagenie's image modifictaion functions

   • Flip image horizontaly or vertically

   flipped_image = flip(image, direction = 1)
   

   • Scale image by a desrired scaling factore

   scaled_image = scale(image, N = 0.4)
   

   • Blur image with a defined standard deviation

   blurred_image = blur(image, stdev = 2.0)
   

   • Convert RGB to graycsaled images

   grayed_image = grayscale(image)
   

Python Ecosystem Integration

This package fits well within the Python ecosystem by providing functionality for image manipulation and augmentation. There are several popular libraries for image processing, that offer more complex functionalities, but this package provides a simple, user-friendly interface for common operations tailored for specific image manipulation tasks.
