原创使用自定义数据集在PyTorch中训练Yolo进行对象检测

在上一个故事中，我展示了如何使用预训练的Yolo网络进行物体检测和跟踪。现在，我想向您展示如何使用由您自己的图像组成的自定义数据集重新训练Yolo。挑战涉及检测隧道网络中的9个不同对象-它们是非常具体的对象，而不是标准Yolo模型中包含的常规对象。在此示例中，我假设只有3个对象类。有几种方法可以执行此操作，并且可以根据官方规范在训练脚本中定义图像，配置，批注和其他数据文件的位置，但这是一种更简单且井井有条的方法 Yolo的最佳做法。Folder Structure首先，您需要使用以下文件夹结构将

原创检测图像中的多个对象并在视频中跟踪它们

现在，我将向您展示如何使用预先训练的分类器来检测图像中的多个对象，然后在视频中跟踪它们。图像分类（识别）和物体检测之间有什么区别？在分类中，您确定图像中的主要对象是什么，整个图像按一个类别进行分类。在检测中，在图像中识别出多个对象，进行分类，并确定位置（作为边界框）。Object Detection in Images有多种对象检测算法，其中最流行的是YOLO和SSD。对于这个故事，我将使用YOLOv3。我不会深入探讨YOLO（只看一次）的工作原理的技术细节-您可以在此处阅读该书-但要专注于如

原创使用OpenCV对物体搜索检测与识别

在本教程中，我们将了解对象检测中称为“选择性搜索”的重要概念。我们还将用C ++和Python共享OpenCV代码。物体检测与物体识别对象识别算法识别图像中存在哪些对象。它将整个图像作为输入，并输出该图像中存在的对象的类标签和类概率。例如，类标签可以是“狗”，相关的类概率可以是97％。另一方面，对象检测算法不仅告诉您图像中存在哪些对象，还输出边界框（x，y，宽度，高度）以指示图像内对象的位置。所有物体检测算法的核心是物体识别算法。假设我们训练了一个物体识别模型，该模型识别图像斑块中的狗。该模型将判断
