Hi I have a histogram which I want to find its min and max. So lets say the first max happens around 0.1 the local mean is at around 0.3 and second local max is at around 0.8.
I use findpeaks command but my first question is how to find a location on horizontal axis after having the index of maxima or minima? (specially for the minima and second max)?
2-How to find location of minimum because findpeaks only gives maximum location?

The usual method is to use findpeaks on the inverted signal, so that what were once valleys (minima) now become peaks.
flippedSignal = max(signal) - signal;
By the way, what does this have to do with image processing?
