face++ API接口调用

标签：isp conf closed face++ jpg nes window 需要 none 人脸识别 首先我想描述一下，在学校的时候一直好奇人脸识别与人脸检测这个技术，之后做了很多实验，曾经使用过很多简单的算法来做人脸相似度对比，比如：夹角余弦算法、判断两个矩阵之间对应位置元素相同来做统计、直方图比对、欧氏距离、绝对值距离等等很多这种低级的实验我都做过，一次次的识别让我感到万分难过。之后我不在最求这种算法的研究了，改成了看别人如何实现的，你也实现出来就好。很多人说这是it从业者的征兆，这样我彻底相信了，因为作为一个it开发的从业工作者，不能什么东西都需要自己开发，公司的要求是尽快的把项目赶出来，才能到达利益最大化。下面我为大家带来我在学校一直实验的人脸识别实现吧。当然我是在调用别人的接口。 1、导入所需要的包 2、定义请求返回数据画出人脸 3、准备好post请求的地址、key、password。 4、对http返回数据进行转换提取 5、画出检测对比的人脸 6、下面是完整代码： face++ API接口调用 标签：isp conf closed face++ jpg nes window 需要 none 原文地址：https://www.cnblogs.com/wuzaipei/p/9471669.html
