此句的threshold表示的是特征向量距离的阈值,距离有可能大于1的
Sorry, something went wrong.
关于人脸特征向量的计算和阈值 的问题,可以参考我发布的另一篇代码:https://github.com/hpc203/libface-detect-recognition 这里面对输出的人脸特征向量做长度归一化,用余弦距离作为相似性度量,这时候距离就都保证在-1到1之间的
No branches or pull requests
在detect_face_align_rec这个Python文件中,此句的threshold表示的是阈值还是一个评分呢,默认是0.65,但是输出发现识别我的图片都在1以上甚至有的达到了2.5以上,跟图片质量有关系么,谢谢
