I am trying to use dlib in android. I integrated dlib in android app and able to get the face landmarks(Detection) but I need to get the encodings(128 points) signature of the face also, in order to (Recognize) the face.
but I couldn't find:
compute_face_descriptor()
or even
face_encodings()
that are used to encode the face.
Any possible solution how to encode detected faces on android?
face_encodings input -> An image that includes a human face and face landmarks (x,y) positions for each landmark:
return [{
"chin": points[0:17],
"left_eyebrow": points[17:22],
"right_eyebrow": points[22:27],
"nose_bridge": points[27:31],
"nose_tip": points[31:36],
"left_eye": points[36:42],
"right_eye": points[42:48],
"top_lip": points[48:55] + [points[64]] + [points[63]] + [points[62]] + [points[61]] + [points[60]],
"bottom_lip": points[54:60] + [points[48]] + [points[60]] + [points[67]] + [points[66]] + [points[65]] + [points[64]]
} for points in landmarks_as_tuples]
(face_encodings output):
return [np.array(face_encoder.compute_face_descriptor(face_image, raw_landmark_set, num_jitters)) for raw_landmark_set in raw_landmarks]

What I want, is to implement face_encodings function on android
(native c++).
I would like to understand why a variable of type com.ibm.jms.JMSTextMessage is printed with truncated content and ellipses (...) when converted to string.
I have this code in a JSR223 Sampler in JMeter:

TextMessage msg = sessInboundQueue.createTextMessage()
msg.setText(payload)
log.info(msg.toString())
log.info(msg.getClass().toString())
log.info(msg.getText())
I would like to understand why log.info(msg.toString()) does not print the whole text content and show ellipses after some point (...)
If I do log.info(msg.getText()), I can see the whole text message.
Here is the print outcome in jmeter's console:

According to the IBM documentation com.ibm.jms.JMSTextMessage inherits the toString() implementation from com.ibm.jms.JMSMessage and the JavaDoc for that method says:
Gets a String containing a formatted version of the message header.
My guess is that the body is cut off simply because toString() is really just meant to give you the header. However, only IBM would know for sure why it works that way. To be clear, there is no guarantee that toString() will (or should) return the entire body of the message.
If you really want to inspect the body of the text message you should invoke getText(). This method is required to return the body of the text-message according to the JMS JavaDoc as well as IBM's own JavaDoc. Both state:
Gets the String containing this message's data. The default value is null.
I have written a piece of code in Java that connect to S3 and read list of files in the bucket. I tested the code and is working properly (in both local and EC2). However, when I run the code in EMR I face this error:
"java.util.concurrent.TimeoutException: Futures timed out after [100000 milliseconds]
I get suspected it can be because of ClientConfiguration and I increased all of the Timeout, RequestTimeout and SocketTimeOut to 5 minutes, but still not change and again I get the same error. What can be reason of this error? The content of bucket is big, but in client mode in EC2, I can read all of them in 3 minutes! something should be wrong!
and this is my code:
try {
ListVersionsRequest request = new ListVersionsRequest().withBucketName(bucketname).withPrefix(prefix)
.withMaxResults(999999);
VersionListing versionListing;
do {
versionListing = s3.listVersions(request);
for (S3VersionSummary versionSummary : versionListing.getVersionSummaries()) {
if (conditions.length != 0)
if (contain_str(versionSummary.getKey(), conditions))
collect.add("s3://" + bucketname + "/" + versionSummary.getKey());
else
continue;
else
collect.add("s3://" + bucketname + "/" + versionSummary.getKey());
}
request.setKeyMarker(versionListing.getNextKeyMarker());
request.setVersionIdMarker(versionListing.getNextVersionIdMarker());
} while (versionListing.isTruncated()); //check remaining pagination
}
catch (AmazonServiceException ase) {
System.out.println("Caught an AmazonServiceException, " +
"which means your request made it " +
"to Amazon S3, but was rejected with an error response " +
"for some reason.");
System.out.println("Error Message: " + ase.getMessage());
System.out.println("HTTP Status Code: " + ase.getStatusCode());
System.out.println("AWS Error Code: " + ase.getErrorCode());
System.out.println("Error Type: " + ase.getErrorType());
System.out.println("Request ID: " + ase.getRequestId());
} catch (AmazonClientException ace) {
System.out.println("Caught an AmazonClientException, " +
"which means the client encountered " +
"an internal error while trying to communicate" +
" with S3, " +
"such as not being able to access the network.");
System.out.println("Error Message: " + ace.getMessage());
}
finally {
Collections.shuffle(collect); //randomizing the file orders
if (collect.size() * percentage < 1) // if sample number is less than 1 take the whole data
percentage = 1;
collect2 = collect.subList(0, (int) (collect.size() * percentage)); //take the samples
return String.join(",", collect2);
}
And the error:

SOLVED & WHY:
Path to image contains Unicode character, I have to say it's a bug.
ORIGINAL POST:
I am new to OpenCV and just use java with OpenCV 3.2.0, 3.1.0, and 2.4.3 to read this image without any success, namely, no width or height can be read, though my aim is to find the harris corners, and use other image is without this problem.
code:

SOLVED & WHY:
Path to image contains Unicode character.
As someone suggests if you solve your problem, delete it or answer it.
If you try to read image from Unicode path, errors occur, and I didn't see related solution, so you can read this.
OpenCV is bugged with Unicode file path, sadly. That's the problem of OpenCV but mine.
I am using Java 7, and I have the following code that uses the jsondiffpatch Javascript library:
logger.debug("CURRENT PATH=" + Paths.get("").toAbsolutePath());
ScriptEngine engine = new ScriptEngineManager().getEngineByName("JavaScript");
reader = new FileReader("webclient/common/js/jsondiffpatch.min.js");
engine.eval(reader);
If you look at line 48 of jsondiffpatch.js (the uncompressed version of jsondiffpatch.min.js), you can see it references another module:
var packageInfoModuleName = '../package.json';
When executing the Java code, the engine.eval(reader) line can't find package.json and throws the following exception:

The jsondiffpatch.min.js file is located in the webclient/common/js directory, and the package.json file is located in the webclient/common directory.
The logger.debug line printed out the following for the current working directory:
CURRENT PATH=/usr/local/project/version/Software
So I tried copying the package.json file to the /usr/local/project/version directory, and I still got the same exception.
Why can't the ScriptEngine find the package.json file?
the jsondiffpatch.js file found in /public/build is a bundle (created with browserify) intended only for using it in a browser (the require function called there is defined at the top of the file, it doesn't read files from disc).
I'm not familiar with Java ScriptEngine, but it looks it's not allowing a redefine of the require function. if it supports CommonJS, you shouldn't use the bundled version, you should require ./src/main.js (the library main module, as pointed in package.json)
(Disclaimer: I'm jsondiffpatch author)
Attempt to try the full path of the module you want to include.
I used Java 8, Nashorn, nashorn-commonjs-modules, jsondiffpatch.js.
I deleted chalk external module and package.json from the file main.js because it's outside the scope of my Nashorn base folder.
It's work now :)
