Dear forum followers I have a issue which I don't know how deal with it.
I'm developing a tracker (track people in videos) from a particle filter. I have particles along the image and I cluster them using EM (http://docs.opencv.org/modules/ml/doc/expectation_maximization.html#ml-expectation-maximization) in Opencv.
After clustering, I can check the next values about the output clusters:
- Mean of the cluster (position)
- Weight of the cluster
- Covariance of the clusters
At this point everything is fine.
After I modify some of this clusters and particles and the final step would be recalculate mean, weight and covariance. I calculcate these variables:
- Mean: calculating the average position of the particles.
- Covariance: calculateing the covariance of the particles.
- Weight: here is my doubt... HOW can I calculate the weight of each cluster??
I hope you can help me!!! Thank in advanced!!!
