this algorithm uses approximate entropy index's projection pursuit based on real coding genetic optimize algorithm ( rcgoa-pp ) to project the targets information hided in the high-dimensional data into low-dimensional space and then extract small targets with histogram image segmentation method 該算法用基于近似相對熵的實碼遺傳優(yōu)化投影尋蹤方法(rcgoa-pp),有效地將高維數(shù)據(jù)中隱藏的目標信息集中投影到低維空間中,并用直方圖分割的方法提取出小目標。
