I am adding image in gallery by getting image from gallery using enroll api.
Now for recognition I am using recognition api.If I pick same image from gallery ,Its giving me result properly.But I pick other image of same person (That is face is same as image i have enrolled) ,its giving me no result found .please help.
I'm getting a java.net.SocketTimeoutException. Previous requests and calls done with kairos have been successful. When I'm deleting a user from a particular gallery, all is functioning well. It appears the java.net.SocketTimeoutException appears only when I try to Verify or Enroll images.
What could be the cause?
Hi
I tried to enroll a face when the network is turned off (Its works perfect when the network is ON). I get a NullPointerException and app crashes. I've put try-catch around enroll method but I it's still the same. Is there a way to handle this exception?
My Code:
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
photo = (Bitmap) data.getExtras().get("data");
String subjectId = nameInput.getText().toString();
String galleryId = serialNo;
String selector = "FULL";
String multipleFaces = "true";
String minHeadScale = "0.25";
try {
myKairos.enroll(photo,
subjectId,
galleryId,
selector,
multipleFaces,
minHeadScale,
listener);
} catch (JSONException | UnsupportedEncodingException | NullPointerException e ) {
e.printStackTrace();
}
}
Runtime error

Enroll request is successful, I see it on Kairos Dashboard. Unfortunately I cannot catch JSON formatted response. I use this class for connection:
public class Connection {
URL url1 = null;
HttpURLConnection httpURLConnection= null;
BufferedReader reader;
String json=null;
public String connect(String url){
try {
url1= new URL(url);
httpURLConnection=(HttpURLConnection)url1.openConnection();
httpURLConnection.connect();
InputStream in = httpURLConnection.getInputStream();
reader=new BufferedReader(new InputStreamReader(in));
StringBuffer buffer= new StringBuffer();
String line="";
while((line=reader.readLine())!=null){
buffer.append(line);
}
json=buffer.toString();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
finally {
if(httpURLConnection!=null){
httpURLConnection.disconnect();
}
if(reader!=null){
try {
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return json;
}
}
Call:
Connection con = new Connection();
parsedString = con.connect("https://api.kairos.com/enroll");
And this for parsing:
try {
JSONObject jsonRootObject = new JSONObject(text);
JSONArray jsonArray = jsonRootObject.optJSONArray("images");
for(int i=0; i < jsonArray.length(); i++){
JSONObject jsonObject = jsonArray.getJSONObject(i);
String status = jsonObject.optString("status").toString();
String face_id = jsonObject.optString("face_id").toString();
toast(status);
toast(face_id);
}
} catch (JSONException e){
e.printStackTrace();
}
I get always NullPointerException for the text string.
How do you run the project? There isn't a build.gradle file.
How should I set up the build.gradle?
In my demo I am adding one image of mine using enroll api with subject id "test".
Now I am again choose same image from gallery and call recognize api ,it's giving me proper response.
But I choose second image of mine (i.e faces of both images are same) but now recognize api giving now search found.pls help about this
Is there any function to backup registered faces? In case application will be used in another devices.
