Functions ¶
func EqualizeHist ¶
EqualizeHist equalizes the histogram of the input image to normalize the brightness and increases the contrast of the image.
func GaussianBlur ¶
GaussianBlur computes and returns an image with an applied Gaussian filter. Both kernel and sigma are parameters used for generating a Gaussian filter kernel.
