The standard deviation ‚Äö√Ñ√∂‚à ö√ë‚à ö‚⧂âà √¨‚à ö√¢‚Äö√Ñ√∂‚à ö√ë‚à ö¬• at any point in image averaging: ‚âà √¨‚à ö√¢¬¨‚à ë‚Äö√†√®¬¨‚à û(x, y) = 1/‚Äö√Ñ√∂‚à ö‚Ć‚à ö‚à ÇK ‚âà √¨‚à ö√¢‚Äö√Ѭ∂‚Äö√¢‚Ä¢(x, y), where ¬¨‚à ë‚Äö√†√®¬¨‚à û(x, y) is the average image formed by averaging K different noisy images and ‚Äö√Ѭ∂‚Äö√¢‚Ä¢(x, y) is the noise added to an original image f(x, y).
