pyaesthetics.selfsimilarity.preprocess_image

pyaesthetics.selfsimilarity.preprocess_image(image_path)

Open an image, convert it to LAB color space, split into L, a, and b channels, and calculate the gradient of each channel. Then merge the gradients by taking the maximum value for each pixel from the three gradients.

Parameters:

image_path – Path to the input image.

Returns:

Merged gradient image.
