For the noise of underwater image, a kind of scale-invariant feature extraction algorithm is proposed which hold the anti-noise characteristics and based on Harris comer and Gaussian scale space. We extract the Harris corners in different scale.

"Once we scale up, algorithms must be sensitive to tiny changes in identities and at the same time invariant to lighting, pose, age," Kemelmacher-Shlizerman said.
凯梅尔马赫·施勒泽曼说：“一旦扩大规模，算法必须对身份的细微变化敏感，同时不受光照、姿势和年龄影响。”
He found that these neural avalanches are scale invariant and that their size obeys a power law.
他发现这些神经雪崩是规模不变的，还有它们的大小遵循幂次定律。
The avalanches are "scale invariant", which means that avalanches of all possible sizes occur.
雪崩是“规模不变”的，这意味着所有有可能的大大小小的雪崩都会发生。
