android - Parsing char to vector<float> for hog.setSVMdetector(vector<float>) -

i have problem parsing float char in jni-android application.this sample data :

and type of data vector<float> hog.setsvmdetector(const vector<float>& detector):

0.05359386f, -0.14721455f, -0.05532170f, 0.05077307f, 0.11547081f, -0.04268804f, 0.04635834f, -0.05468199f, 0.08232084f, 0.10424068f, -0.02294518f, 0.01108519f, 0.01378693f, 0.11193510f, 0.01268418f, 0.08528346f, -0.06309239f, 0.13054633f, 0.08100729f, -0.05209739f, -0.04315529f, 0.09341384f, 0.11035026f, -0.07596218f 

this sample code .cpp in jni :

extern "c" jboolean java_com_example_franksyesipangkar_tourguide_camerapreview_imageprocessing (jnienv* env, jobject thiz, jint width, jint height, jbytearray nv21framedata, jintarray outpixels, jbytearray b)  {  logd("jnienv");      //convert jbytearray char     jbyte *cmd = env->getbytearrayelements(b, 0);     logd("jnienvfeature");      //char * feature = (char *)cmd;      char feature[90600];     memset(feature,0, sizeof(feature));     memcpy(feature, cmd, strlen((char*)cmd)); 

in code, data in char feature want parsing data type of data hog.setsvmdetector(const vector<float>& detector).so, have idea ?

maybe can you:

#include <iostream> #include <vector> #include <strstream> #include <string>   std::vector<float> parse_delimeted_list_of_numbers(char* line, char delimeter) {     std::vector<float> vector_of_numbers;     std::istrstream input_stream(line);     std::string text;     float number;     while (std::getline(input_stream, text, delimeter)) {         sscanf_s(text.c_str(), "%f", &number, text.size());         vector_of_numbers.push_back(number);     }     return vector_of_numbers; }  // program test above function works int _tmain(int argc, _tchar* argv[]) { //  auto vector_of_numbers = parse_delimeted_list_of_numbers("234.0, 345, 465, 46456.0",',');     auto vector_of_numbers = parse_delimeted_list_of_numbers("234.0 34 465 46456.0", ' ');     (auto number : vector_of_numbers)         std::cout << number << "\n";     return 0; }
