Processes of identification of pipette. (a) Grayscale image of a pipette and cell; (b) image obtained after dilation followed by erosion; (c) binary image of the pipette; (d) the blobs which are not connected to the boundary (indicated by red arrows in (c)) are filled with black pixels; (e) only the blob which has the longest distance in the x-direction is left; (f) the tip of the pipette is successfully identified.
