Official pytorch implementation of SIM: Semantic-aware Instance Mask Generation for Box-Supervised Instance Segmentation (CVPR 2023) - lslrh/SIM
文章用ROI pooling提取box中的特征,同时将特征图转化到特定大小,然后是两个全连接层,第一个全连接层将特征维度降低到256,第二个全连接层回归像素级的mask,由m2维矢量参数化,此层有m2个输出,每个输出执行对掩模的二进制logistic回归。因为此阶段输入有第一阶段的box,所以loss函数也会受第一阶段限制,此阶段loss函数...
2). Regressing Mask-level Instances 该阶段的输出是对每一个box的proposal进行像素级的mask分割。 Given a box predicted by stage 1, we extract a feature of this box byRegion-of-Interest (RoI) pooling. The purpose of RoI pooling is for producing a fixed-size feature from an arbitrary box, wh...
To introduce translation-variant property, a fully convolutional solution is firstly proposed in [5] for instance mask proposal. It uses k^2 position-sensitive score maps that correspond to k × k evenly partitioned cells of objects. This is illustrated in Figure 1(b) (k = 3). Each score...
实例分割初探,Fully Convolutional Instance-aware Semantic Segmentation论文解读 进入2017年之后,深度学习计算机视觉领域有了新的发展。在以往的研究中,深度神经网络往往是单任务的,比如图像分类(AlexNet, VGG16等等),图像分割(以FCN为代表的一众论文),目标检测(R-CNN,Fast R-CNN和Fatser R-CNN,以及后来的YOLO和SSD,...
InstanceFCN主要是用来生成mask proposal,也有着一些缺点,比如无法判断语义类别,需要一个后续的网络辅助判别,也就是说它不是一个end to end的结构。 建立在InstanceFCN的基础上,作者提出了他们的结构(即FCIS)。FCIS的两个子任务(目标分割和检测)不仅共享卷积特征,也共享score maps。 在实例分割,同一像素既可以是一...
We present the first fully convolutional end-to-end solution for instance-aware semantic segmentation task. It inherits all the merits of FCNs for semantic segmentation [29] and instance mask proposal [5]. It performs instance mask prediction and classification jointly. The underlying convolutional re...

Fully Convolutional Instance-aware Semantic Segmentation PaperCode 主要基于: - FCNs for Semantic Segmentation 基于FCN的语义分割. 传统FCNs卷积具有平移不变性, 但实例分割需要平移可变. - instance mask proposal 实例 mask 候选 现阶段instance semantic segmentation 方法: 1. 整张图像进行FCN处理,得到中间的共享fe...
In this work, we use recent advances in conditional diffusion modeling to formulate a first-of-its-kind nuclei-aware semantic tissue generation framework (NASDM) which can synthesize realistic tissue samples given a semantic instance mask of up to six different nuclei types, enabling pixel-perfect...
