Instance segmentation, which is a subset of the larger field of image segmentation, provides more detailed and sophisticated output than conventional object detection algorithms. Other image segmentation tasks includesemantic segmentation, which categorizes each pixel in an image by semantic class–the cat...
? 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, ...
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:文章里面比较多公式,方法不算特别常规吧。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的问题。那么 R...
Rank 损失并没有变,和上面说的一样。N_{FP}代表所有负例中大于该正例 logit 的数量,rank 代表所有正例和负例中大于等于该正例的数量。作者额外增加了一个 Sort 损失,针对正例内部中的候选框区别,即对所有正例大于该正例 logit 数量做一个加权平均,值为 1-IoU 的值。直观意思就是那些越正确的候选框给予...
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box进行平均运算,得到最后的box,而且并不是对所有的点进行平均,而是预测ROI内所有的点的前景/背景分类,只有前景的点才参与平均运算,背景点不参与平均运算...

Instance segmentation is the task of detecting and segmenting objects in images. See different approaches to instance segmentation, including Mask R-CNN.
Object detection and instance segmentation are by far the most important fields of applications in Computer Vision. However, detection of small objects and inference on large images are still major issues in practical usage. Here comes the SAHI to help developers overcome these real-world problems ...
