Image Functions

Image functions/utilities.

image_functions.image_functions.compare_images(image1_path: str, image2_path: str) → None[source]

Compare two images using multiple techniques:

  • SHA-256 hash comparison (byte-level)

  • Pixel-by-pixel comparison using Pillow (ImageChops)

  • Structural Similarity Index (SSIM) using scikit-image

  • ImageMagick ‘compare’ with Absolute Error (AE) metric

Outputs detailed results and stores an ImageMagick diff image in a unique temporary folder based on a UUID.

Parameters:

  • image1_path (str) – Path to the first image.

  • image2_path (str) – Path to the second image.

image_functions.image_functions.sha256_hash(filepath: str) → str[source]

Compute the SHA-256 hash of a file.
