libjpeg vs libjpeg-turbo

With the first exercise I've the opportunity to compare libjpeg vs libjpeg-turbo.

Before to install libjpeg-turbo I made a backup with the standard one, so it's a great moment to compare both

The code used is the same in both cases (Contours) and here are the results

libjpeg-turbo

libjpeg

	libjpeg	libjpeg-turbo
Load	199	63
2Gray	61	45
Trheshold	12	12
Create	32	11
find	53	31
Draw	47	47
Total	404	209

Finally the libjpeg-turbo is faster than libjpeg, we will check in the future what happen with Linaro vs Raspbian.

By the moment I'll be working with Raspbian with libjpe-turbo
