Simply not displaying what the camera sees - Android Face Detection [closed]
Hi there,
I added a TL;DR (too long didn't read) at the bottom for the lazy:
I want to do some OpenGL on top of OpenCV.
I am using from openCV - andoid - sample applications, the face detection sample code. \adt-bundle-windows-x86_64-20131030\OpenCV-2.4.7-android-sdk\samples\face-detection This code comes bundled with OpenCV-andoid and I have it working on my mobile device (exciting!)
I would like this application to run as normal, except with no visualization. In this way I hope to "hide" the OpenCV portion and only display what I am doing with OpenGL
My first (failed) approach was to make a new layout NewView.xml file, and then simply setContentView(NewView.xml) . Then in theory, the OpenCV would continue running, and I could display text on the displayed NewView.xml the position of the face it is detecting.
Now lets back up for a second. With the untouched original sample code, there is a method called "public Mat onCameraFrame(CvCameraViewFrame inputFrame)" that gets executed on every loop. I was able to play with the OpenCV visualizations by injecting my own code inside this method.
So it seemed logical for me to update my text on NewView.xml in this area: ... TextView t = (TextView)findViewById(R.id.textView1); t.setText("Something Else"); ... Unfortunately "Something Else" never gets displayed.
TL;DR: I would like to decouple the layout xml file from the OpenCV java so that the camera image does not get displayed. It's being a little challenging. Using from openCV - andoid - sample applications, the face detection sample code.
