拒绝造轮子，所以当然要选择开源库。
由于是mtk功能机平台，只支持c，所以c++和java什么的就不考虑了。
二维码的编码，选择了qrencode，这个移植比较简单，不多说。
二维码的扫描算法，走了一些弯路。一开始根据网上的扫描算法速度对比，选择了quirc。但是移植好了实际上机测试，完全不是那回事，速度慢的要死，十几秒没反应，机器直接重启了。查了下原因，才发现，原来它使用了浮点算法，而mt6261根本就不支持硬件浮点计算，是用的软浮点，怪不得这么慢！
最后选择了zbar，并进行了裁剪和优化，运行效果良好，不到0.5秒就能完成从扫描到识别出二维码的操作。
源码就不贴出来了，外包项目，代码还是要适当保密。

Could you transfer $1000 from my current account to my deposit account? http://radiopentecostesrd.com/santa-gladys-3/ stromectol ivermectin "Many collectors build their collections around a particular theme, perhaps the place of their birth, a certain county or school, or indeed the place in which they themselves have over the years enjoyed holidaying. Prices for the vast majority of pieces to be found in the marketplace are low in real terms, and should not prove a barrier to anyone considering collecting in this field."
Could you ask him to call me? http://diamondexchangeindia.com/2021/07/30/how-to-make-world777-user-id-in-hindi/ stromectol ivermectin Early indications were that all the women I know loved Haunter, whereas men were less enthusiastic; some actively hated it. I started wondering if perhaps they found it hard to identify with a teenage girl protagonist, or if there might be something intrinsically feminine about ghost stories, whose bailiwick is the gothic novel and the old dark house, repository of secret chambers, keys and other Freudian symbols...
