Title: 'DCT space' scaling experiment

This experiment is to perform a 1/8th scaling of a jpeg image by keeping each DC coefficient (the 1st value in an 8x8 block) and not performing the iDCT. Since the DC coefficient is representative of the entire 8x8 block, we can use it directly without having to read any other AC coefficients or performing any inverse DCT.
