Histogram equation
WebbHistogram Equalization. Histogram of an image is the graphical representation of the distribution of intensities of pixels. It provides an estimate of where pixel values are concentrated and whether there are unusual deviations. e.g. - Consider the following image. Say, all pixel values have a depth of 2 bits and are unsigned. WebbA frequency distribution (histogram) created from Gaussian data will look like a bell-shaped Gaussian distribution. ... and then choose the "Gaussian" equation from the "Gaussian" family of equations. Model (Gaussian distribution) Y=Amplitude*exp(-0.5*((X-Mean)/SD)^2) Amplitude is the height of the center of the distribution in Y units.
