写了两个易语言找图的方法，一个是大漠内存找图，另一个是opencv找图。
循环10次，对比找图的准确度和速度。

全屏找图

先来看全屏找图的速度。
手机的屏幕是750×1334 px；为了方便传输，统一将图片缩小一半，即375×667 px；
先来测试在压缩后的图片上找图。

使用的大漠插件版本，是v7.2336

测试代码：

.版本 2

.计次循环首 (10, )
    ios.findImg (“Res\Small\apple\title_设置.jpg”)
    ios.findImg_dm (“Res\Small\apple\title_设置.jpg”)
.计次循环尾 ()

可以看到，opencv找图耗时平均在25ms，大漠内存找图平均耗时5ms。
全屏找图的情况下，大漠内存找图比opencv找图速度要快5倍左右。

区域找图

测试代码：

.版本 2

.计次循环首 (10, )
    ios.findImg (“Res\Small\apple\title_设置.jpg”, “[10,60,100,110]”)
    ios.findImg_dm (“Res\Small\apple\title_设置.jpg”, “[10,60,100,110]”)
.计次循环尾 ()

可以看到，这轮测试中，二者的找图速度都在0或者1毫秒。
经过多轮测试，区域找图的情况下，大漠内存找图比opencv找图速度要快1倍左右。

找图准确度

从上面的日志可以看出，二者的找图准确度都是一样的，都返回了找到的索引和找到的小图左上角坐标。
可能是因为找图的特征比较简单，所以无法精确的对比准确度。
