> Hello Imagej users,
>
> I am just starting in image processing field. I recorded a process with a
> camera. The process is characterized by the appearance of a dark area in a very
> bright one. The position , the size and the shape of the dark area is variable.
> My aim is to identify a set of pictures I can use to describe and characterize
> the process by evaluating the number of pictures in the sequence that are
> looking similar to each type of picture of the set.
> I have already identified the set of picture. As criteria, I took the position
> and the size of the dark area.
> to obtain the position, used the following funtion:
> -smooth
> -find edges
> .binary-theshold
> invert
> -find maxima within a certain noise tolerance.
>
> Now I would like to implement a macro to classfy my sequence according to the
> similarity with each pictures of the set.
>
> One example of conclusion I am looking for is for example" in a sequence of 20
> pictures, and a set of 3 pictures taken as samples, 12 are similar to sample1, 3
> to sample2 and 5 to sample 3"
>
>
> My question is doea anyone help me to define which criteria I should used to
> loop inside the sequence for a comparison?
>
> -I tried to plot the profile for each sample and compare it with the profile of
> each picture of the sample but the samples profiles are too similar so I can
> used the profile as criteria.
> .- the second Idea was to find the minima/maxima in each picture and compare the
> position with the position in each sample this does not work because the aim is
> to identify an area not a point.
> -third Idea, to track the shape of the dark area for each picture and compare
> with the samples, but the dark area shape and position are not so stable and I
> dont know how to define a tolerance for comparison.

> can anyone offer me a suitable solution, any idea is welcomed
