if helps you, here ribs masks connected one. rib masks:

as can see, ribs aren't vertical, can rotated too. need detect bent ones (for example third rib left in image). please have idea how it?

i have tried distance transform find center of rib , working 1d function, whole rib 50 pixels wide, noise big - function has peaks use derivatives or approximation. next, wanted try hough-lines on upper , lower part separately, details looking (as can see, bent not big) small method.

all need "is bent" or "is not bent". @ moment, have no other ideas how detect bent ribs. pleased idea.

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
