Scale Invariance

Definition

Scale invariance refers to the property of a system or process that remains unchanged when scaled by a certain factor. In the context of optical pattern recognition and classification, this concept is crucial because it allows for the accurate identification of patterns regardless of their size or resolution. This means that systems designed with scale invariance can recognize and classify patterns consistently, enabling them to be effective in diverse applications ranging from image processing to complex data analysis.
