Deep learning与传统的神经网络之间有相同的地方也有很多不同:二者的相同在于deep learning采用了神经网络相似的分层结构,系统由包括输入层、隐层(多层)、输出层组成的多层网络,只有相邻层节点之间有连接,同一层以及跨层节点之间相互无连接,每一层可以看作是一个logistic regression模型;这种分层结构,是比较接近人类大脑的...

These methods use edge detection algorithms, such as the Canny edge detector, to identify edges and segment objects based on the detected edges. 3. Region-Based Methods Region-based methods group pixels into regions based on their similarity in color, texture, or other features. These methods ...
An accurate stereo matching method based on color segments and edges 2023, Pattern Recognition Citation Excerpt : Table 1 shows formulae for the disparity of different types of stimulus bars. Edge matching is also important, and researchers have given some methods, such as the edge line-based ma...
[5] Devil's on the Edges: Selective Quad Attention for Scene Graph Generation 标题:边缘的魔鬼:...
Used architecture do not support instance segmentation. We deliberately didn’t use Mask-RCNN, because the quality of segmentation near object edges is low. That’s why we decided to make a two-steps scheme: apply Faster-RCNN (based on NasNet) to detect all persons on images, and...

其中P是正样本集合,N是负样本集合。可以看到对比上述的损失函数,该损失函数开始考虑一个样本集合的问题。但是,并不是所有样本对之间的negative edges都携带了有用的信息,也就是说随机采样的样本对之间的negative edges携带了非常有限的信息,因此我们需要设计一种非随机的采样方法。
