There are already some blog post regarding convolution in deep learning, but I found all of them highly confusing with unnecessary mathematical details that do not further the understanding in any meaningful way. This blog post will also have many mathematical details, but I will approach them fro...
Consider our example of using a convolution to detect edges in an image, above, by sliding a kernel around and applying it to every patch. Just like this, a convolutional layer will apply a neuron to every patch of the image. Conclusion We introduced a lot of mathematical machinery in this...

Xception: Deep Learning with Depthwise Separable Convolutions个人理解 Xception: Deep Learning with Depthwise Separable Convolutions 提出背景: 在Inception结构提出时,作者通过BottleNeck方法减小卷积操作的计算量,即在特征图输入Inception模块之前添加1x1的卷积层对特征图的通道关系进行映射减小通道数,从而减小运算量。但...
3 Impact of Deep Learning on Image Segmentation 卷积神经网络或深度自编码等深度学习算法的发展不仅影响了目标分类等典型任务,而且在目标检测、定位、跟踪或图像分割等其他相关任务中也很有效。 3.1 Effectiveness of convolutions for segmentation 作为一种操作,卷积可以简单地定义为在将较小的核卷积到较大的图像上...
In another approach, frame-level action detection is effectively formulated as the per-frame action labeling task. We combine two reverse operations (i.e. convolution and deconvolution) into a joint Convolutional-De-Convolutional (CDC) filter, which simultaneously conducts downsampling in space and ...
CSRNet 由两部分构成:前半部分为卷积神经网络CNN,作为2D特征提取器,后半部分使用空洞卷积(Dilated Convolution)来增大感受野,并代替池化层。由于全卷积的结构,CSRNet很容易训练。文章在4个数据集上对CSRNet进行了测试,并取得了当... 根据设计瞄点标度而论文解读the Effective Receptive Field...
This is the standard definition2 of convolution. To make this a bit more concrete, we can think about this in terms of positions the ball might land. After the first drop, it will land at an intermediate position a with probability f(a). If it lands at a, it has prob...
针对语义分割问题,我们从两个方面进行改善,一个是dense upsampling convolution (DUC) 代替 Bilinear upsampling,另一个是用 hybrid dilated convolution (HDC) 代替 传统的 dilated convolution。 3.1. Dense Upsampling Convolution (DUC) 输入图像经过CNN卷积网络模型提取得到的特征层,尺寸减小了很多倍。但是由于语义分割...
Finally, to calculate the gradient w.r.t to the filter maps, we rely on the border handling convolution operation again and flip the error matrix the same way we flip the filters in the convolutional layer. (5) (6) where a(l) is the input to the l-th layer, and a(1) is the...
