Android Question Find point with certain color in video

[Adamdam]

Dear All,
Greetings,

I try to find a code to search for point with certain color in video, say find laser red/or green pointer to track it, hope to make that in real time.
I think this link may the start, by capture the each frame image into buffer (array) and then search inside this buffer for certain color.

best regards

You can use OpenCV for this.
