translucent Particle seperation from background #3

Open jellespijker opened 9 years ago

Neural network where the input is the chromatic a and b of the current pixel and neighbors (maybe described as statistics) the network is learned by letting the user mark the particles... And letting that be the outcome.

Use the threshold value of the previous calculated pixel.... As an memory function loop input and output

Maybe it's wise to segment the fore- / background using conventional OTSU thresholding method and use this and starting point

Jochem you seemed interested in tackling this problem. Just one of the ideas I had but didn't have time to follow through on. (Don't feel obliged, this is just me trying out some github functionality)

In matlab I noticed a grouping when the chromatic value a and b (CIE Lab) when set against each other. When I removed the background and made the same graph with just the particle a region of ab values that was clearly defined was removed. Maybe this is something to be explored 08-06-2015 20_43 office lens
