QUESTION

How to make smoother borders using Fragment shader in OpenGL?

Asked 2021-Nov-28 at 16:45

I have been trying to draw border of an Image with transparent background using OpenGL in Android. I am using Fragment Shader & Vertex Shader. (From the GPUImage Library)

Below I have added Fig. A & Fig B.

Fig A.

Fig B.

I have achieved Fig A. With the customised Fragment Shader. But Unable to make the border smoother as in Fig B. I am attaching the Shader code that I have used (to achieve rough border). Can someone here help me on how to make the border smoother?

Here is my Vertex Shader :

In my filters, the smoothness is achieved by a simple boxblur on the border.. You have decided that alpha > 0.4 is a border. The value of alpha between 0-0.4 in surrounding pixels gives an edge. Just blur this edge with a 3x3 window to get the smooth edge.

To apply the filters mentioned in your comment I've written a sample app with the following :

First you need to create a GPUImageFilterGroup in order to apply all filters mixed :

QUESTION

Is it possible to apply real time filter to android-camerax?

Asked 2020-Jul-26 at 14:13

I'm using cameraX for recording video. I need to apply real time filters to the camera preview using android-gpuimage or any other library. Is it possible? if yes kindly provide an example.

Both video and filtering are not officially supported by CameraX, but you can work around it by encoding the output of ImageAnalysis to video.

The output of ImageAnalysis is YUV420 byte array. It can be converted to Bitmap using this code snippet, and then you can apply GPUImage filter against the Bitmap. Then encode a series of Bitmap to a video. This is inefficient on many levels, but it should work.

You can checkout this code sample for filtering CameraX preview with GPUImage: https://github.com/xizhang/camerax-gpuimage
