In the previous blog, I have partly shown some applications of Fourier transform such as edge detection, template matching, etc. Here we show another application which is image enhancement.
The Fourier Transform is a method of converting a signal of dimension X to a signal of dimension 1/X. This method gives way to analyzing signals in terms and their frequencies and provides an easy mathematical manipulation of functions.
Here we discuss the basic implementation of Fourier Transform in Scilab and its applications to images. Continue reading “Fourier Transform and its applications”
One technique in estimating areas from images is through the use of Green’s Theorem. Given a closed region R on the xy plane, its area can be calculated as
