Installation

For Regular Users

Currently, the package is published on PyPI. If you're looking to use VisuMorph without diving into the development, you can easily install it using pip:

pip install visumorph

For Developers

For those interested in contributing or exploring the development version, please follow these steps:

1. Clone the repository:

   git clone https://github.com/UBC-MDS/VisuMorph.git
   

2. Navigate to the cloned directory and install the package in editable mode along with the development dependencies:

   pip install -e .
   

Features

VisuMorph includes a variety of functions for image manipulation:

• Flipping(flip): Horizontally or vertically flip images, useful for creating mirror effects or correcting orientation.
• Rotating(rotate): Rotate images by a specified degree, supporting both clockwise and anticlockwise rotations.
• Hue Change(change_hue): Adjust the hue of images, allowing for color shifting and mood setting in visuals.
• Scaling(scale): Resize images, either uniformly or non-uniformly, without losing the essence of the visual content.

Quick Start Examples

For a quick glimpse into what VisuMorph can do, here are a few simple examples:

Flip an Image

Flip an image horizontally or vertically. This example flips an image horizontally.

import visumorph as vm

# Load your image
img = vm.load_image("path/to/image.jpg")

# Flip the image horizontally
flipped_img = vm.flip(img, v=0)

# Save the flipped image
flipped_img.save("path/to/flipped_image.jpg")

Rotate an Image

Rotate an image by a specified angle in degrees. This example rotates an image by 90 degrees.

import visumorph as vm

# Load your image
img = vm.load_image("path/to/image.jpg")

# Rotate the image by 90 degrees
rotated_img = vm.rotate(img, rotation=90)

# Save the rotated image
rotated_img.save("path/to/rotated_image.jpg")

Change Image Hue

Change the hue of an image. This example changes the hue by a delta value.

import visumorph as vm

# Load your image
img = vm.load_image("path/to/image.jpg")

# Change the hue of the image
hue_changed_img = vm.change_hue(img, delta_hue=0.3)

# Save the hue-changed image
hue_changed_img.save("path/to/hue_changed_image.jpg")

Scale an Image

Scale an image by a specified factor. This example enlarges the image by 20%.

import visumorph as vm

# Load your image
img = vm.load_image("path/to/image.jpg")

# Scale the image by 1.2 times
scaled_img = vm.scale(img, scale=1.2)

# Save the scaled image
scaled_img.save("path/to/scaled_image.jpg")

Make sure to replace "path/to/image.jpg" and the save paths with the actual paths to your image files and desired output locations.

Running Tests

To ensure VisuMorph works as expected, we've included a suite of tests. You can run these tests using pytest to verify the installation and functionality:

pytest --cov=visumorph

If a coverage report is desired, you can run the above command with an extra arugment:

pytest --cov=visumorph --cov-report=xml

Position in the Python Ecosystem

VisuMorph, while a robust tool for image manipulation, is designed primarily as an educational project for the 524 course in the Master of Data Science program. It serves as an introductory tool for those beginning their journey in data science and image processing. While it offers a range of functionalities, it is more limited in scope compared to professional-grade packages like PIL (Python Imaging Library) and OpenCV. These larger libraries offer a wider range of complex functionalities and are suited for industrial applications. However, VisuMorph stands out for its simplicity and ease of use, making it an excellent starting point for students and hobbyists looking to understand the basics of image manipulation in Python.
