MATLAB RGB to LAB Color Space Conversion: Complete Code Example

Using Matlab's 'colorspace' function, you can easily convert RGB values to LAB values. Here's a complete code example:

rgb = [45.75, 120.11, 62.45];
lab = colorspace('RGB->Lab', rgb);

In this code:

• rgb is a 1x3 vector representing the Red, Green, and Blue channel values.
• lab is also a 1x3 vector representing the Lightness, a-axis (green-red), and b-axis (blue-yellow) values.

After running the code, the lab value will be approximately [41.40, -41.20, 23.06].

This code demonstrates a simple conversion from RGB to LAB using MATLAB. You can adapt it to convert any RGB values to LAB for various color processing tasks.
