Splitting an object in an image into segments
显示 更早的评论
I have a number of wavy lines in a logical image. Using bwlabel I am able to get the individual pixel indices for each line.
I was wondering if there is a way to select, on a single line, where you want to split it into segments, and return the pixel indices separately for the each segment a line is split into?

I'd probably use riopolyold() to let the user select where she wants to split the blob - draw a region around the middle. Then use inpolygon() on the PixelIdxList returned from regionprops to determine if a given pixel in the blob is in the polygon (so it's in the middle third drawn by the user) or which side it's on.

In one I don't know...
But using few lines, after bwlabel, I would use regionprops with area propertie...In a third line, cut that piece of the matrix...
