Abstract: Provided herein is a topological derivatives (TDs)-based image segmentation method and system using heterogeneous image features data. The image segmentation method according to an embodiment of the present disclosure involves calculating TDs having each of the heterogeneous image features data as an input value, and segmenting an image into a plurality of regions using the calculated TDs. Accordingly, performance may be improved, and robustness against noise may be further improved.

Abstract: Provided herein is a robust region segmentation method and a system using the same, the method including receiving setting of an image in an input image; calculating representative values for each of an internal portion and an external portion of the region; calculating a cost by substituting the representative values and a pixel value of the image in a cost function, and updating the region based on the calculated cost, wherein the cost function includes a term in which a difference between the updated pixel value and an original pixel value is reflected, thereby enabling an accurate region segmentation even in ambiguous images that are complicated and where division of regions is unclear.

Abstract: The present invention relates to a method for making 3D stereo digital broadcast service compatible in an MPEG-2-TS format which is used for transmitting and receiving digital TV. To this end, suggested is a method for transmitting detailed information which supports both TS-level multiplexing and ES-level multiplexing when left and right compressed bitstreams are multiplexed, when service compatibility is enabled.
