WebFeb 24, 2024 · The resulting image, from applying Contraharmonic Mean Filter on the image with salt and pepper noise, is shown below. Upon comparison with the original grayscale image, we can see that it has reproduced pretty much the exact same image as the original one. Its intensity/brightness level is the same and it highlights the bright spots … In mathematics, the harmonic mean is one of several kinds of average, and in particular, one of the Pythagorean means. It is sometimes appropriate for situations when the average rate is desired. The harmonic mean can be expressed as the reciprocal of the arithmetic mean of the reciprocals of the given set of observations. As a simple example, the harmonic mean of 1, 4, and 4 is boots discounts codes
