[Insight-users] questions about spatial objects & line extraction

[juhaas]

hey everyone,

i´m still new and i still have some problems. could please anybody help me?

in need to extract lines (straight and circled lines) from an image of a 
domino tile. so far, i did some preprocessing and the sobel edge 
detection. after that i binarized the image and did a line thinning. so 
now i have a binary image with the contours of a rectangle and circles.

what i want to do now is to extract these lines. i thought i could maybe 
use the SpatialObject classes or the ChainCodePath. but i have no clue 
how i could get my lines from the image into a SpatialObject or 
ChainCode data structure.

to be honest i don´t understand the use of the SpatialObject at all. is 
this class actually useful to stor segmentation results like this? or 
can you only create some "artificial" models of simple objects?

i feel really lost right now in this huge library.

thanks for any help,
judith
