It removes singleton dimensions from an array.

For example, it will take a 7 x 1 x 300 array and "squeeze" it into a 7 x 300 array.

The full documentation is here.

In this particular case, assuming that Image is an rgb image, it converts a 1 x 1 x 3 vector, into a 3 x 1 vector of RGB intensity at pixel (i,j)
