    5858Earlier mean-shift algorithm uses fixed bandwidth. Fixed bandwidth could result in either over-segment or under-segment. In the literature of Deng et al., 2015  and [http://doi.org/10.1049/iet-ipr.2013.0195 Zhang et al., 2014], each paper proposed an adaptive bandwidth method. [http://doi.org/10.1049/iet-ipr.2014.0393 Zhou et al., 2015] proposed another method, which use smaller bandwidth at first to over-segment the image, then use image clustering, region-based mode merging again to refine the result.
