Abstract
This paper presents a method of implementing the perspective transform as specified in the MPEG-4 standard using 32-bit fixed-point reduced precision calculations instead of using 64-bit floating-point full precision operators. We achieve this by removing some redundant calculations and truncating the numerator and denominator terms of the transform without loss of accuracy.
