QUESTION
I am trying to identify the holes in the target and score them accordingly. I have tried to find contours and it does a lot of work but it did not give me the 100% result. Sometimes it gives me an accurate result and sometimes it misses some bullets. I do not know how to do it. I am new in open CV and image processing. May be its due to the live streaming of the camera and light frequency. Kindly help me to solve this problem.
Details of my target
- top is 6 feet from the ground surface
- camera is 1 feet from the ground level

Here is my code to get video from the camera:

I noticed the perspective seems to have changed a little between your two example shots so rather than do that I tried the following code:
QUESTION
I am trying to achieve user-controlled panning for any number of simultaneous web audio sources. The sources themselves are mono. I'm working in Javascript with the web audio API (https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API).
Currently, the problem I'm running into is that I'm trying to use a multi-channel output (one for each source), but the channel interpretation is overriding my attempts at panning (see https://developer.mozilla.org/en-US/docs/Web/API/AudioNode/channelInterpretation), leading me to think I'm doing something wrong architecturally.
I'd like to leave things at a mostly conceptual level here, since I believe that's where my problem lies.
Current Setup
My approach to this involves having one node handle all the processing for every source, called 'scriptNode' here. A number of channels equal to the number of audio sources is created, and a similarly equal number of panner nodes are created as well. The graph looks like this:

always produces stereo output. When you connect the panner output to one of the input to a merger, the stereo output from the panner is downmixed to mono, effectively removing much of the panning effect.
Some information is missing, but I don't see why you need a merger. You can send the stereo output from each panner directly to the destination. The destination will mix the stereo output from each panner appropriately, preserving the panning effect.
