I have implemented a GPU version of Pica which is high quailty image resizer.

The GPU version of Pica achieves the same anti-moiré effect and sharpness as the original Pica while improving performance by 2-10×, with greater speedup for larger images. Additionally, because the GPU implementation avoids creating extra buffers, memory usage is lower. CPU load is also significantly reduced, which should help prevent performance bottlenecks.
