[Tech Bites] Importance of Phase in Image Processing

It is widely known that images are composed of pixels representing brightness. But what is less known is that images can also be viewed as a combinations of wavelengths of varying frequencies. As seen in the video below, image processing based on a two-dimensional(2D) wave frequencies and their directionality is called Fourier transform. https://vimeo.com/710178524/0c5f06d6bdFigure 1 : …
