YoloV1(anchor-based): 是官方第一版yolo模型,它使用单个卷积神经网络分支对单张图像直接做目标检测和分类,并不像R-CNN系列累的两阶段检测第一步先提取候选框(ROI, regions of interest),第二步再对这些候选框做分类.所以其速度比同期的二阶段模型低更快,但精度要低. yolov2, yolov3都是重点提升yolov1的检测...

目标检测任务是计算机视觉领域的一大任务,依据是否有候选框(Region Proposal)大致可以分为两阶段目标检测(Two-stage Object Detection)与一阶段目标检测(One-Stage Object Detection)。两阶段目标检测模型以Faster R-CNN为代表,特点是精度高但速度慢;一阶段目标检测模型以YOLO系列为代表,其特点是速度快但精度略逊。YOLO的...
