DSSD : Deconvolutional Single Shot Detector论文阅读笔记2017 Abstract 本文的主要贡献是提出了一种方法,将额外的context引入到SOTA通用的目标检测中。==实验中,我们首先将一种SOTA分类器(ResNet-101)和快速检测框架SSD进行组合。然后我们增加了反卷积层来引入额外的大尺度context,提升了准确率,尤
: Single Shot MultiBox Detector Abstract:呈现了一个使用单深度神经网络检测图像目标的方法。方法被命名为SSD,将边界框的输出空间离散化为在每一个特征图位置上的具有不同比例和尺度一组默认框。预测阶段,网络为每一个默认框中每一个对象类别的存在情况都输出一个得分,并对框进行调整来匹配对象的形状。另外,网络...
效果较好的网络依赖于迁移学习,可以获得更高的准确率,同时,拟合的会更快,而DSSD没有预训练模型,因此,无法利用迁移学习的优势,另一方面是反卷积十分吃计算资源,特别是将以前层的信息添加到反卷积的过程中。 Deconvolution Module:为了将前层网络的信息与反卷积层进行融合,本文提出了反卷积模型,如下图,该模型嵌入在整...
1. 我们提出了SSD,一个多分类单杆检测器(single-shot detector),比现在的单杆检测器(YOLO)更快,和那些较慢技术精度一样,并且超过了区域提议(region proposals)和池化(pooling)的方法,包括faster R-CNN. 2. SSD的核心部分是预测分类得分和一个固定集合的默认边界框的框偏移,这些是通过使用卷积滤波器到特征图上...

single-shot detector. In spite of competitive scores, those feature pyramid based methods still suffer from the inconsistency across different scales, which limits the further performance gain. To address this, [38, 45] set the corresponding regions of adjacent levels as ignore regions (i.e. zero...
we propose an automatic polyp detection algorithm based on Single ShotMultibox Detector (SSD). Method. In the paper, SSD is based on VGG-16, the fully connected layer is changed to aconvolutional layer, and four convolutional layers with successively decreasing scales are added as a new network...
