# Single Complex Average

## Contents

## Algorithm Description

Calculates the average of 2 or more images and takes the magnitude image and phase image as input to reduce the noise and enhance the quality of an image by averaging multiple images.

## Single Complex Average Input

**Phase Gap**-work only under “Complex Average” Model means after start Mag File, how many files to go to get to the first phase image. It is applicable when Magnitude and phase are in one series AND start phase File not input.**How Many Average Times to Go**-work only under “continuous Images Average”Model means the number of average images to be produced.**How Many images in Once average**-work only under “continuous Images Average”Model means the number of images to be considered for a single average.

- Case 1: Normal Average Operation is chosen with continuous Images Average, magnitude average for continous magnitude images.

- Case 2: Normal Average method is chosen with Jump Images Average, magnitude average for any input magnitude images.

- Case 3: Complex Average Operation is chosen with continuous Images Average, complex average for continous magnitude images and their corresponding phase images.

- Case 4: Complex Average Operation is chosen with Jump Images Average,complex average for any input magnitude images and their corresponding phase images.

## Single Complex Average Output

For case 1 and case 2, only produce averaged magnitude images, for case 3 and case 4, produce averaged magnitude images and their corresponding phase images.
