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.

遗传算法
遗传算法（Genetic Algorithm，GA）起源于对生物系统所进行的计算机模拟研究[7]。它是模仿自然界生物进化机制发展起来的随机全局搜索和优化方法，借鉴了达尔文的进化论和孟德尔的遗传学说。其本质是一种高效、并行、全局搜索的方法，能在搜索过程中自动获取和积累有关搜索空间的知识，并自适应地控制搜索过程以求得最佳解。如优化灰色模型[8-9]。因此利用遗传算法对BP神经网络模型进行优化，从而提高预测精度以及训练速度[10-12]。利用优化后的模型以及初始模型对油田实际数据进行训练以及测试，对比模型优化前后的预测精度以及训练速度。
