Abstract

In this work the interpolation filter using truncated raised cosine pulses for image resizing is investigated. The rectangular-truncated raised cosine pulse with rolloff factor β ≥ 0.5 and truncation length T ≥ 4T S is shown to be a good choice for interpolation. The experimental result reveals that with a comparable computational complexity the truncated raised cosine interpolator is superior to the widely used interpolator with Keys' cubic function. The result also reveals that the performance of truncated raised cosine interpolator is only slightly worse than that of the least-square cubic B-spline interpolator, but with much lower computational or hardware complexity.
