问题 I am using the text recognition API within mobile vision, and trying to work with currency amounts. The OCR currently supports Latin based languages like French, German, etc., so I figured the country's currency (Euro) would be a recognized symbol, but as far as I can tell, it's not. Are there language preferences that I should be changing in order to detect €? Does anyone have experience working with currency symbols within mobile vision as well, or is it just not currently supported? Thanks

问题 I would like to perform face detection / tracking on a video file (e.g. an MP4 from the users gallery) using the Android Vision FaceDetector API. I can see many examples on using the CameraSource class to perform face tracking on the stream coming directly from the camera (e.g. on the android-vision github), but nothing on video files. I tried looking at the source code for CameraSource through Android Studio, but it is obfuscated, and I couldn't see the original online. I image there are

问题 The similar question has been asked here: Add 2D or 3D Face Filters like MSQRD/SnapChat Using Google Vision API for iOS. However, it has not been answered yet. Essentially, my work assignment is to put a 3D face filter on a person's face while the phone's front-facing camera is being used. Given that the Mobile Vision API/the GitHub Android Vision project provide a way to detect a human face and stick some drawable images on it, but what my users want is a 3D object (cat or dog face) like

问题 I have checkout out the latest Google Vision APIs from here: https://github.com/googlesamples/android-vision And I am running it on a LG G2 device with KitKat. The only change I have made is to the minSdkVerion in the Gradle file: ... defaultConfig { applicationId "com.google.android.gms.samples.vision.face.multitracker" minSdkVersion 19 ... However it does not focus. How do I make it focus? 回答1: I modified the CameraSourcePreview (....) constructor to be as follows: public

问题 I am using the FaceTracker sample from the Android vision API. However, I am experiencing difficulty in recording videos while the overlays are drawn on them. One way is to store bitmaps as images and process them using FFmpeg or Xuggler to merge them as videos, but I am wondering if there is a better solution to this problem if we can record video at runtime as the preview is projected. Update 1: I updated the following class with media recorder, but the recording is still not working. It is

问题 Good day all, I am using Google's new Face API (Link here) which works with improved FaceDetection. One of the things you get back is a List of Landmark objects, each of which has an X and Y coordinate to use. With these coordinates, I am trying to figure out the center of the picture, but figuring out the correct numbers is proving difficult. Here is what I know so far: 1) Unlike in the old ways, it is no longer 1000, 1000 by -1000, -1000 2) The coordinates that are returned are in float
