我正在使用android中的opencv。实际上我在opencv做眼睛检测,并希望实时改变眼睛的颜色。例如:通过前置摄像头眼睛瞳孔被剔除并改变瞳孔颜色。我在设置Hue频道时遇到问题。请帮助
Mat eyeball_HSV = new Mat();
Mat dest = new Mat();
Mat eye = new Mat();
eye = mRgba.submat(eye_template).clone();
List<Mat> hsv_channel = new ArrayList<Mat>();
//convert image to HSV
// Imgproc.cvtColor(eye, eyeball_RGB, Imgproc.COLOR_RGBA2RGB, 3);
Imgproc.cvtColor(eye, eyeball_HSV, Imgproc.COLOR_RGB2HSV, 0);
//Core.inRange(eyeball_HSV, new Scalar(90, 50, 50), new Scalar(130, 255, 255), dest);
// get HSV channel
//hsv_channel[0] is hue
//hsv_channel[1] is saturation
//hsv_channel[2] is visibility
Core.split(eyeball_HSV, hsv_channel);
try
{
hsv_channel.get(0).setTo(new Scalar(145));
Log.v(TAG, "Got the Channel!");
}
catch(Exception ex)
{
ex.printStackTrace();
Log.v(TAG, "Didn't get any channel");
}
Imgproc.cvtColor(eyeball_HSV, dest, Imgproc.COLOR_HSV2RGB);
Imgproc.cvtColor(dest, eye, Imgproc.COLOR_RGB2RGBA);
