1. A method for image improvement comprising the following steps not necessarily in sequential order: providing a series of frames of a given region of interest; determining the value of each pixel at each location within each frame to form a pixel value array for each frame; summing the pixel values in each frame to obtain the frame intensity for each frame; multiplying the pixels in pixel value array by the frame intensity to produce a frame intensity multiplied pixel value array; summing the frame intensity multiplied pixel value arrays together and dividing by the number of frames to obtain an average of the frame intensity multiplied pixel value arrays; using the pixel value arrays, creating an array of average pixel values; determining the average frame intensity for the series of frames; multiplying the array of average pixel values by the average frame intensity for all of the inputted frames; and subtracting the array of average pixel values multiplied by average frame intensity from the average of the frame intensity multiplied pixel value arrays to provide an array of modified pixel values to form an improved image.
