i’m trying to analyse an image with affdex SDK (like the seconde example done by Abdelrahman Mahmoud link for tutorial ) i’m using raspberry pi 3b running Raspbian stretch with gcc 6.3.0
the code :
#include <iostream>
#include <string>
#include "Magick++.h"
#include "PhotoDetector.h"
class Listener : public affdex::ImageListener{
void onImageResults(std::map<affdex::FaceId,affdex::Face> faces,affdex::Frame image){
std::cout << "Found Faces: "<< faces.size() << std::endl;
for (auto pair : faces){
std::string pronoun="they";
std::string emotion="neutral";
affdex::Face face=pair.second;
if(face.appearance.gender == affdex::Gender::Male){
pronoun="He";
}
else if(face.appearance.gender == affdex::Gender::Female){
pronoun="She";
}
if(face.emotions.joy>25){
emotion="Happy :)";
}
else if(face.emotions.sadness>25){
emotion="Sad :(";
}
std::cout << face.id << " : " << pronoun << " looks " << emotion << std::endl;
}
};
void onImageCapture(affdex::Frame image){};
};
int main(int argc, char ** argsv)
{
//Initialize the imagemagick library
Magick::InitializeMagick(*argsv);
// Read Image into Memory
Magick::Image img(argsv[1]);
char * pixels = new char [img.columns() * img.rows() * 1];
img.write(0,0,img.columns(), img.rows(), "RGB", MagickCore::StorageType::CharPixel, pixels);
affdex::Frame frame(img.columns(), img.rows(), pixels, affdex::Frame::COLOR_FORMAT::BGR);
affdex::PhotoDetector detector(1);
affdex::ImageListener * listen = new Listener();
detector.setImageListener(listen);
detector.setClassifierPath("/home/pi/affdex-sdk/data");
detector.setDetectAllEmotions(true);
detector.setDetectAllAppearances(true);
detector.setDetectAllExpressions(true);
detector.start();
detector.process(frame);
detector.stop();
delete listen;
delete [] pixels;
return 0;
}
when i run the script with
./test-app image.jpg
i got this error (the same if i use .bmp image ):
segmentation fault
i tried with an other image and i got this error :
terminate called after throwing an instance of ‘Magick::ErrorResourceLimit’ ** what(): test-app: memory allocation failed `download.png’ @ error/png.c/ReadOnePNGImage/2341 Aborted
Any pointers, thanks
The pixels
buffer isn't large enough to accept all the data.
size_t pixels_size = img.columns() // Width
* img.rows() // Height
* sizeof(char) // Size of storage
* 3; // Number of parts per pixel ("RGB")
char * pixels = new char [pixels_size];
img.write(0,0,img.columns(), img.rows(), "RGB", MagickCore::StorageType::CharPixel, pixels);
