Area Correlation Library performance test (arecorlib - p2)

research (correct, but but not optimized yet) code for area correlation in image processing, implemented on C++(with Qt4).
- int32 and double types used
- Qt4 types for images used

AMD K10 (2.8GHz) - 810-920ms
ARM Cortex -A8(550MHz) - 8919 - 15850ms

Unbiased render & GPU

it's time:

first was LuxRender

- 0.8 support a GPU (under Linux - AMD Radeon)

- ~2.5 times for AMD Athlon X4 (2.7GHz) vs NVidia GeForce GT460


Indigo since 3.0 also support GPU

- CPU: 103025.85289 samples / second (9.70630 micro-seconds / sample)

- CPU+GPU: 225543.72788 samples / second (4.43373 micro-seconds / sample)

also a bit more than 2 times speedup for such hardware


only Maxwell render not support GPU (yet, I guess)
