PromptMatch – Competitive image-prompting with similarity scoring

Summary: PromptMatch is a game where users write prompts to recreate a target image and receive a score based on content, color, and structure similarity. It uses neural-net embeddings, HSV histograms, and HOG-style layout comparisons to evaluate results, enabling users to improve prompt engineering through various timed and unlimited modes.

What it does

Users view a target image, write a prompt to generate a similar image, and receive a score combining CLIP embeddings for content, HSV histograms for color, and HOG-style layout for structure.

Who it's for

It is designed for individuals seeking to practice and enhance their image prompt writing skills through competitive and replayable challenges.

Why it matters

It provides a practical method to measure and improve prompt quality by quantifying similarity between generated and target images.
