Android Vision Face Detection with Video Stream

由 做~自己de王妃 提交于 2019-12-10 19:14:41
问题 I am trying to integrate the face detection api in a video stream I am receiving from a parrot bebop drone. The stream is decoded with the MediaCodec class (http://developer.android.com/reference/android/media/MediaCodec.html) and this is working fine. Rather than rendering the decoded frame data to a surface view, I can successfully access the ByteBuffer with the decoded frame data from the decoder. I can also access the decoded image objects (class https://developer.android.com/reference

QR Codes - raw binary data

由 ▼魔方 西西 提交于 2019-12-08 04:41:34
问题 Does anybody know if there is a way to get the raw binary data of a QR code using the android vision API ? The QR codes I am reading have binary data (including NUL characters) in them but are built with 8 bit encoding so the full binary data block is there. The Barcode object returned very helpfully has the string "Unknown encoding" in the rawValue field, instead of my binary data ? Thanks for any ideas! 回答1: To answer my own question, it seems both the android vision and zxing libraries

Does Machine Vision API work offline?

由 邮差的信 提交于 2019-12-06 20:18:39
问题 Does the Google Mobile Vision (https://developers.google.com/vision/) API work offline? Or does it need Internet connectivity? The sample app does not require any Internet permission. Which means the API works entirely offline. I am looking for a positive confirmation of this. PS. Also I am looking for more information on this API. For example, does it use neural networks? If so what algorithms were used? I can not find any detail discussion anywhere. 回答1: The API does an initial library

How to install the barcode scanning library without a google account?

由 可紊 提交于 2019-12-06 19:46:01
问题 I would like to install the android-vision portion of google play services on devices that are not allowed to have a google account signed in. Traditionally, the android-vision library is downloaded through the play store as an update to google play services. According to this, the package name should be com.google.android.gms.vision.barcode. I used adb to list all packages installed on my rooted nexus device that has the barcode scanning library downloaded and the package was not in the list

Preview size for barcode scanner from vision api

由 三世轮回 提交于 2019-12-06 19:31:51
问题 I'm using the barcode-reader example from Google's Android Vision API. The preview size doesn't seem to fill up the whole space available (I'm using a Nexus 4 and there is a white unused space to the right of preview, about 1/3 of the width). I would like to be able to run this example on various devices and always have it fill up the whole space available. So the bit I've been playing with is: CameraSource.Builder builder = new CameraSource.Builder(getApplicationContext(), barcodeDetector)
