Join Patrick Royal for an in-depth discussion in this video Working with images, part of Learning MATLAB (2013).
When most people hear the term "matrix", they don't tend to associate it with an …image However, a matrix is precisely what an image is. …It's a two-dimensional collection of values corresponding with pixels of color. …As a result, MATLAB can actually import an image just as it would an Excel spreadsheet. …And can work with the data within as if were purely numerical. …To import an image, double-click on it in your active folder. …In this example, I'll import the file named building.jpg in exercise files.…
These specific format of an image matrix depends on the file format itself. …But the most common format is RGB, where each pixel contains three values …corresponding to a saturation in red, green and blue colors. …As a result, MATLAB models this image as a three dimensional matrix. …The first two dimensions correspond to the height and width of an image, and the …third is always equal to three, so that each pixel can have the correct three …values stored in it. Modifying an image is a complicated …
