? 2022 Elsevier B.V.In this paper, we propose a simple and effective Common-and-Differential Attention Network (CDANet) for object detection and instance segmentation. For an input intermediate feature map, CDANet infers parallelly attention modules along channel and spatial dimensions respectively, ...
D2Det是一种two-stage算法,类似于Faster-RCNN,在Faster-RCNN的基础上进行了一些改进,总体框架如下图(a)所示: 和Faster-RCNN相比,改进的地方在于: 1. Dense local regression 如上图(b)所示,Faster-RCNN是对RPN提出的ROI进行卷积操作,对提出的box进行NMS操作,得到最后的结果,而D2Det是对ROI内所有的点提出的b...
Rank & Sort Loss for Object Detection and Instance Segmentation 这篇文章算是我读的 detection 文章里面比较难理解的,原因可能在于:创新的点跟普通的也不太一样;文章里面比较多公式。但之前也有跟这方面的工作如 AP Loss、aLRPLoss 等。它们都是为了解决一个问题:单阶段目标检测器分类和回归在训练和预测不一致...
forest:由于构造parent class的方式不唯一,本文构建了多个tree形成classification forest ,其中每个tree进行vote NMS Resampling:instance level,re-balance the data distribution,alleviate the imbalanced learning caused by the long-tail phenomena Forest RCNN Problem Formulation ...
最后可以参考一下与传统方法对比的损失结构图: 实验结果 在COCO minival 数据集上的实验结果;H# 为参数比较排序 与其他损失函数的实验结果对比 在COCO test-dev 数据集上的实验结果 论文信息 Rank & Sort Loss for Object Detection and Instance Segmentation...

目标检测(Object Detection) 实例分割(Instance Segmentation) 一、语义分割 语义分割任务目标是输入一个图像,然后对每个像素都进行分类,如下图左,将一些像素分类为填空,一些分类为树等等。需要注意的是,语义分割单纯地对每个像素分类,因此不会区分同类目标,比如下图右边有两头牛,但是分类的结果中不会将两头牛区分开来...
Recognition, classification, semantic image segmentation, instance segmentation, object detection using features, and deep learning object detection using CNNs, YOLO, and SSD
Since the MaskRCNN-benchmark of facebook is deprecated, we suggest to use our mmdetection based res2net for object detection and instance segmentation to get the SOTA performance on both two tasks.https://github.com/Res2Net/mmdetection
In object detection, the intersection over union (IoU) threshold is frequently used to define positives/negatives. The threshold used to train a detector defines its extit{quality}. While the commonly used threshold of 0.5 leads to noisy (low-quality) detections, detection performance frequently de...
