:fire:利用Mobilenetssd目标检测框架,ncnn前向推理,android项目
I tried most versions
1.ncnn for android的时候,ANDROID_PLATFPRM=android-14,是安卓4.0系统的意思嘛,如果我是安卓6.0的系统,是改成Android-16就行了吗
2.android studio的使用,在新建工程的时候,phone and tablet也要选跟上面对应的系统嘛,比如教程里面交叉编译的是andriod-4.0系统,在AS里面也必须选4.0系统与之对应,对吗

你好
在MobileNetssd.cpp文件中
opt.num_threads = 4; //线程 这里可以修改
你有没有尝试过修改为1,2,4看看cpu占用率的情况?
我这里无论怎么修改CPU占用率都是60-70%左右,
但是我想设置为1,把CPU占用率降到20%左右。
change this line to : jfloatArray jOutputData = env->NewFloatArray(output_wsize * output_hsize);
你好,我想问一下, MobileNetSSD_deploy.id.h这个文件是哪里来的啊?自己写的还是ncnn源码编译出来的?我在ncnn的那个PC端demo中没看到这个文件
然后cpp/Mobilenetssd/include里面的文件是怎么得到的我也不太清楚,希望解答一下~谢谢
工程和配套blog都很详细
非常感谢
我想把你的项目信息放在 ncnn readme 中作为例子
请问下,我用MobileNetSSD_demo 这个demo在android上运行
加载完模型直接返回,重复多次,内存一直在涨。
请问这是哪里有问题?
