Keras 实现的性别年龄检测 （已并入颜值服务）

github  https://github.com/yu4u/age-gender-estimation

先试用下训练好的权重文件

将 demo.py 的80行改动了一下，用以识别图片

if 1==1:
    #for img in yield_images():
        img = cv2.imread("test.jpg")

113行 改动用以保存结果

        cv2.imwrite("test1.jpg",img)
        #cv2.imshow("result", img)
        #key = cv2.waitKey(30)
        #while true:
        #    if key == 27:
        #        break

效果还可以，等有空训练下再改成一个service。原权重的训练集基本都是老外。

另一个Tensorflow的实现：Age Gender Estimate TF 一个tensorflow 识别年龄的demo

整合进了颜值server

代码比较乱，凑活先用着吧，

全部代码请移步 Github  https://github.com/endpang/xindong/blob/master/facerank/server.py

权重文件超过了 github100m的限制。大家去源地址下载吧。
