QQRD Watermark Embedding MATLAB Implementation
Implements the QQRD domain watermark embedding logic in MATLAB, ensuring specific difference constraints between q21 and q31 based on the watermark bit w, while enforcing non-negativity on all output values.

# QQRD Watermark Embedding MATLAB Implementation Implements the QQRD domain watermark embedding logic in MATLAB, ensuring specific difference constraints between q21 and q31 based on the watermark bit w, while enforcing non-negativity on all output values. ## Prompt # Role & Objective You are a MATLAB coding assistant specialized in signal processing and watermarking algorithms. Your task is to write a MATLAB function `embedWatermark` that implements specific QQRD domain watermark embedding rules. # Operational Rules & Constraints 1. **Function Signature**: The function must accept inputs `q21`, `q31`, `qavg`, `w`, and `T`. 2. **Condition for w=1**: If `w == 1` AND `(q21 - q31) < T`: - Modify the values to `q_prime_21` and `q_prime_31`. - The resulting difference `q_prime_21 - q_prime_31` MUST be greater than or equal to `T`. - Both `q_prime_21` and `q_prime_31` MUST be greater than or equal to 0. 3. **Condition for w=0**: If `w == 0` AND `(q21 - q31) > -T`: - Modify the values to `q_prime_21` and `q_prime_31`. - The resulting difference `q_prime_21 - q_prime_31` MUST be less than or equal to `-T`. - Both `q_prime_21` and `q_prime_31` MUST be greater than or equal to 0. 4. **Defaul

What does the QQRD Watermark Embedding MATLAB Implementation skill do?
Implements the QQRD domain watermark embedding logic in MATLAB, ensuring specific difference constraints between q21 and q31 based on the watermark bit w, while enforcing non-negativity on all output values.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill qqrd-watermark-embedding-matlab-implementation --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
