In an effort to understand the benefits and drawbacks of existing methods, we empirically compare five state-of-the-art superpixel algorithms for their ability to adhere to image boundaries, speed, memory efficiency, and their impact on segmentation performance. We then introduce a new superpixel algorithm, simple linear iterative clustering (SLIC), which adapts a k-means clustering approach to efficiently generate superpixels. Despite its simplicity, SLIC adheres to boundaries as well as or better than previous methods. At the same time, it is faster and more memory efficient, improves segmentation performance, and is straightforward to extend to supervoxel generation. 000177415 6531_ $$aSuperpixels 000177415 6531_ $$aSegmentation 000177415 6531_ $$aClustering 000177415 6531_ $$ak-means 000177415 6531_ $$aNCCR-MICS/EMSP 000177415 6531_ $$aNCCR-MICS 000177415 700__ $$0242495$$aAchanta, Radhakrishna$$g172126 000177415 700__ $$0245251$$aShaji, Appu$$g188751 000177415 700__ $$0242712$$aSmith, Kevin$$g163328 000177415 700__ $$0242715$$aLucchi, Aurélien$$g185205 000177415 700__ $$0240252$$aFua, Pascal$$g112366 000177415 700__ $$0241946$$aSüsstrunk, Sabine$$g125681 000177415 773__ $$j34$$k11$$q2274-2282$$tIEEE Transactions on Pattern Analysis and Machine Intelligence 000177415 8564_ $$uhttp://ivrg.epfl.ch/research/superpixels$$zURL 000177415 8564_ $$s8910790$$uhttps://infoscience.epfl.ch/record/177415/files/Superpixel_PAMI2011-2.pdf$$yn/a$$zn/a 000177415 909C0 $$0252320$$pIVRL$$xU10429 000177415 909C0 $$0252087$$pCVLAB$$xU10659 000177415 909CO $$ooai:infoscience.tind.io:177415$$pIC$$particle$$qGLOBAL_SET 000177415 917Z8 $$x125681 000177415 917Z8 $$x125681 000177415 917Z8 $$x125681 000177415 937__ $$aEPFL-ARTICLE-177415 000177415 973__ $$aEPFL$$rREVIEWED$$sPUBLISHED 000177415 980__ $$aARTICLE
