Once we have the annotation file, Run the following python script to extract the objects (logo in our case) and resize them to the same size. It seems the smaller the size of the object the better it is interms of training time and accuracy. Also try to get objects from as many imag...

最近在微信公众号里看到多篇讲解yolov5在openvino部署做目标检测文章,但是没看到过用opencv的dnn模块做yolov5目标检测的。于是,我就想着编写一套用opencv的dnn模块做yolov5目标检测的程序。在编写这套程序时,遇到的bug和解决办法,在这篇文章里讲述一下。 在yolov5之前的yolov3和yolov4的官方代码都是基于darknet框架的...

Object Detection 对象检测是一种与计算机视觉、图像处理和深度学习相关的计算机技术,用于检测图像和视频中的对象实例 目标检测算法的任务是找出图像中所有感兴趣的目标(物体),确定他们的类别和位置。 计算机视觉中的图像分类获取图像并预测图像中的对象,而对象检测不仅可以预测对象,还可以根据边界框找到它们的位置。 例如...

Therefore, a sliding window based approach for object detection was ruled out. It was just too expensive. Researchers started working on a new idea of training a machine learning model that could propose locations of bounding boxes that contained objects. These bounding boxes were called Region Pro...
