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.
