Overview

This Python module provides utility functions for various image processing tasks, such as image conversion, display, normalization, and enhancement. It leverages the power of libraries like cv2 and numpy to handle and manipulate image data.

Functions

open_img

• Purpose: Convert the image to a specified color space.
• Inputs: Image data (or path), desired color space, and data type specifications.
• Output: Image converted to the specified color space.

display

• Purpose: Display images with their labels.
• Inputs: Multiple images and labels, display size and layout specifications.
• Output: None, this displays the image.

normalize_img

• Purpose: Normalize an image.
• Inputs: Image data.
• Output: Normalized image.

flatten_unflatten

• Purpose: Flatten or reshape an image.
• Inputs: Image data, operation type (flatten or reshape), and desired shape if reshaping.
• Output: Flattened or reshaped image.

binary

• Purpose: Convert an image to a binary format based on a threshold.
• Inputs: Image data and threshold value.
• Output: Binarized image.

img2blocs

• Purpose: Split an image into blocks/blocs of a certain size.
• Inputs: Image data, block size, and padding type.
• Output: List of blocks/blocs.

resize_img

• Purpose: Resize an image to the specified dimensions.
• Inputs: Image data and desired dimensions (width & height).
• Output: Resized image.

rotate_img

• Purpose: Rotate an image by a specified angle.
• Inputs: Image data and rotation angle.
• Output: Rotated image.

enhance_img

• Purpose: Enhance an image by adding noise, applying blur, and adjusting contrast.
• Inputs: Image data, and specifications for noise, blur, and contrast adjustments.
• Output: Enhanced image.

Requirements

• cv2
• numpy
• matplotlib

Usage

In order to install the library:

pip install image-processing-lib

To use it, nothing is more simple:

import image_processing.functions as ip

# Load an image
image = ip.open_img('PATH_TO_THE_IMAGE', 'GRAY')

# Use any of the provided functions
processed_image = FUNCTION_NAME(image, ...other_args)
