Generating synthetic images using Scilab

Scilab is a programming platform that has similar functions with that of MATLAB, only that it’s open-source.

Images, in computer ‘language’, are just matrices of numbers corresponding to pixel values.  Scilab is a useful tool in manipulating images because it can do a lot of matrix operations with only a few lines of codes.

Finding values of digitally scanned plots

This activity is from one of my applied physics courses which deals with image processing methods.

Given digitally scanned plots such as hand-drawn historical or old plots or even the computer generated ones, you could get the values by simple ratio and proportion. This sounds so simple but takes a lot of time and focus.
