How to reshape the mean vector to a 2D mean face image in matlab?

Answer 1

[Kaashyap Pappu]

You can use the reshape function to change the vector into a 2-Dimensional array. Following this, you can use the imagesc function to plot the image, where each array value is represented using the appropriate colourmap.

While reshaping, it is important to note that MATLAB’s vector indexing follows a column-major approach.

Hope this helps!
