		| Abstract: | 
		We present a shape select algorithm for searching merging galaxies among large astronomical
 surveys. Galaxy mergers usually have complex structures and exhibit irregular shapes, thus
 searching irregular pattern might be a practical approach to select possible merger candidates
 among large survey data. We use binarization technique to determine the shape of detected objects
 and quantify it into a set of shape descriptors. With these descriptors we can locate relatively
 irregular objects as possible merger candidates for further visual inspection. |
