ColorBasedWatershedSegmentationofLowAltitudeAeria
we introduce the Color-based Catchment
Basin Merging Algorithm, an area-based segmentation approach
that is specifically designed to segment low-altitude
aerial images, as a preprocessing step to 3D reconstruction.
This approach extends the watershed-based Catchment
Basin Merging Algorithm, which is purely geometric,
by introducing color similarity as an additional criterion to
decide on the merging of evolving regions. Experiments performed
with real aerial images of varied nature demonstrate
that this modification eliminates over-segmentation problems
of the existing algorithm, allowing large-scale urban
scenes to be segmented in an accurate, reliable and fully automatic
way.

摘 要:提出一种新的基于Pareto多目标进化免疫算法(PMEIA)。算法在每一代进化群体中选取最优非支配抗体保存到记忆细胞文档中 同时引入Parzen窗估计法计算记忆细胞的熵值,根据熵值对记忆细胞文档进行动更新,使算法向着理想Pareto最优边界搜索。此外,算法基于点在目标空间分况进行克隆选择,有利于得到分布较广的Pareto最优边界,且加快了收敛速度。与已有算法相比, PMEIA在收敛性、多样性,以及解的分布性方面都得到很好的提高。(Abstract:This paperproposed a new pareto-based multi-object evolutionary mi mune algorithm(PMEIA). PMEIA selected
optmi alnon-dominated antibodieswhichwere then reserved inmemory cellarchive, and introducedParzenwindow to calculate
entropy ofmemory cells. Updated thememory cell archive according to entropy ofmemory cells. This guarantees the conver-
gence to the true Pareto fron.t Moreover, the performance of clone selection was dependent on distribution in the objective
space, whichwas favorable forgetting awidely spreadPareto frontand mi proving convergence speed. Comparedwith the exis-
ted algorithms, the obtained solutions ofPMEIA havemuch betterperformance in the convergence, diversity and distribution.)
