How to Apply Custom Filters in a Camera [Surfaceview Preview]...?

From the images, it's from a app called Geak Camera. Actually, I developed this app, and I used the GLSurfaceView not the surfaceview. And the app is not maintained now because I left that company. And I updated that app called "U camera".The scale animation was improved in "U camera".


All these manipulations can be performed with OpenCV. Download their basic Android example, and you can add your logic to onCameraFrame() callback.
