Describe what you mean. What does central mean? Is it the pixel at the center of the image, like the pixel at (256,256) of an image 511x511 in size? Or does it mean the average value of the intensities, or the median value. "Central" is very ambigous.

central pixel can be found out by using the line ... med_red (i,j)= median (a2); and same for the other colour component ...

If you define "center pixel intensity" as being the mean red, green, and blue intensity, then one of the approaches is to take the mean of each color plane individually.
If you were looking for "average brightness" then you would take a different approach.
