ANDROID - color detection using openCV - how to?

Question

my goal is to display a threshed image using the HSV color space in a way that only yellow objects will be shown. i use this code (based on a code given by the openCV 2.3.1 andr

Answer 1

I think mHSVThreshed is a binary mat

so maybe this line :

Imgproc.cvtColor(mHSVThreshed, mRgba, Imgproc.COLOR_HSV2RGB, 0);

should change to :

Imgproc.cvtColor(mHSVThreshed, mRgba, Imgproc.COLOR_GRAY2RGB, 0);

I spent a lot of time dealing with the "showing" problem too...

hope this help...
