Matrix factorization is a useful technique in process of image fusion. There are numerous applications of image fusion such as robot/machine vision, aerial military affairs, satellite imaging as well as medical imaging in magnetic resonance imaging (MRI) and positron emission tomography (PET). One of the techniques used for image processing is the Non-negative Matrix Factorization […]

The golden ratio is a mysterious irrational number that appears in mathematics, nature and the arts.

The history of the golden ratio begins with Euclid’s comment in “Elements” about a point divides a line into an “extreme and mean ratio.” Afterward intellectuals began studying this ratio and found several links to other mathematical aspects such as […]
