OpenCV错误“无法填充临时阶段的训练数据集。 进入第三阶段培训后，分支培训终止。”

Question

在搜索此错误时，我仅发现在开始时就发生了这种情况。 就我而言，它发生在三阶段训练的开始。

我正在使用启用了OpenMP的OpenCV 2.4.10。 波纹管是我使用的命令行和输出。 有谁知道如何解决这个问题？

您的负面图片有多大。 我有同样的问题。 该错误表明他没有足够的负面图片。 底片图像不必与底片图像相同。 所以我所做的就是拍摄原始的负片，但是物体上有一个黑色矩形。 并重新开始。

函数负片在图像中搜索新的负​​片图像，当他使用一个负片图像时，他将不再使用它。 它是随机选择的，并且具有与正像相同的大小。
