- 矩形条带装箱问题(RSPP)是指将一组矩形装入在一个宽度固定高度不限的矩形容器中,以期 获得最小装箱高度.RSPP理论上属于NP难问题,在新闻组版、布料下料以及金属切割等工业领域中 有着广泛的应用.为解决该问题,采用了一种混合算法,即将一种新的启发式算法—— 动态匹配算 法—— 与遗传算法结合起来.混合算法中,动态匹配算法能根据4类启发式规则动态选择与装填区域相 匹配的下一个待装矩形,同时将装箱后所需容器高度用遗传算法的进化策略进行优化.对2组标准测试 问题的计算结果表明,相
otsu111
- Otsu算法步骤如下: 设图象包含L个灰度级(0,1…,L-1),灰度值为i的的象素点数为Ni ,图象总的象素点数为N=N0+N1+...+N(L-1)。灰度值为i的点的概率为: P(i) = N(i)/N. 门限t将整幅图象分为暗区c1和亮区c2两类,则类间方差σ是t的函数: σ=a1*a2(u1-u2)^2 (2) 式中,aj 为类cj的面积与图象总面积之比,a1 = sum(P(i)) i->t, a2 = 1-a1 uj为类cj的均值,u1 = sum(i*P(
