stouputils.image package

This module provides little utilities for image processing.

• relative_luminance() - Perceived brightness of a colour, as the sRGB relative luminance.

• readable_text_color() - Pick the text colour that stays readable on a given background.

• auto_crop() - Automatically crop an image to remove zero/uniform regions.

• numpy_segments_to_obj() - Generate a ‘.obj’ file from multiple 3D segmentation arrays, each with its own color.

• numpy_to_gif() - Generate a ‘.gif’ file from a 3D numpy array for visualization.

• numpy_to_obj() - Generate a ‘.obj’ file from a 3D numpy array using marching cubes.

• image_resize() - Resize an image while preserving its aspect ratio by default.
