JND：只是明显的区别
“Just Noticeable Difference”在医学和生理学领域中常被简写为JND，以方便日常书写和快速交流。该术语的中文含义为“仅可察觉的差异”，用于描述能够被人感知到的最小刺激变化或差异程度，是感官测量中的一个重要概念。

例句
- The embedding strength is decided by the just noticeable difference of the image, and the cover image is not needed during the extraction of watermark.
- 水印的嵌入强度由图像的视觉临界差异决定，水印的提取不需要载体图像。
- Some new research methods in social skills such as the Just Noticeable Difference(JND) and Functional Analysis Approach also reviewed in the paper.
- 社会技能研究方法的研究主要包括对现有社会技能评定量表和测量方法的分析与评价以及对新的社会技能研究方法&最小可觉差法和功能分析法的特征分析和有效性评价。
- A spread spectrum based watermarking algorithm is proposed based on Watson model, which calculate the just noticeable difference ( JND ) of sub-block image, then the frequency points insensitive to change are chosen and embedded to improve the robust.
