Color Harmonization

Color Harmonization is a computational model designed to adjust and enhance the color balance of an image based on harmony templates, as proposed in the paper by Daniel Cohen-Or et al. The model improves visual aesthetics by aligning image colors with established color harmony principles. It supports multiple harmony templates and can be integrated with user interfaces for visual quality assessment using metrics from interfacemetrics.aalto.fi.

Input Schema

Input Schema
Field	Type	Description
input_image	URLrequired	The image file on which color processing will be performed.
template	optionsrequired	This is the name of a selected "harmonic color scheme". The template defines a specific color harmony to apply to the image. Available options: [vertical_bar, v_shape, right_angle, left_angle, double_bar, t_shape, y_branch, x_cross]
angle	intrequired	This is an angle value used in the harmonic color scheme to adjust the colors in the image. This value can help shift or modify the color scheme of the image according to the selected template. Min: 1. Max: 90.

Output Schema

Output Schema
Field	Type	Description
output_image	URL	URL to a generated output artifact.
output_hue	URL	URL to a generated output artifact.
