So, how exactly do we adapt the familiar 2-D convolution to 1-D or 3-D? The mechanics of sliding filters to compute weighted sums (the definition of convolution) remain the same. We only change how we move the kernel. In this tutorial, we’ll explore the conceptual similarities and dif...
Each of these can be computed efficiently as convolution with a row and a column vector. CONV2 is used to carry out the individual convolutions. Separable masks are a particular case and are handled by CONVOLVE2 much as FILTER2 does. Many other masks which are not separable have low rank...

An example image-processing application based upon two-dimensional convolution is described and the operating procedures of custom computing machines are presented. Also presented are the details of directly implementing two-dimensional convolution in a straight-forward, systolic fashion in reconfigurable ...
The characteristics of 2-D convolutions with big kernel in low-rank are analysed, and a fast algorithm is given. Then a systolic array implementation, which is derived by a three-stage dependence-graph-based mapping approach, is presented. It is shown that the architecture has a high efficien...
论文名称:D2Conv3D: Dynamic Dilated Convolutions for Object Segmentation in Videos 原文作者:Christian Schmidt 内容提要 尽管单目视频中目标的分割和跟踪受到了研究界的高度重视,但仍有很大的改进空间。现有研究证明了膨胀和变形卷积对于各种图像级分割任务的有效性。这让我们有理由相信,这种卷积的3D扩展也可以提高视...
Note thatfspecialshifts the equation to ensure that the sum of all elements of the kernel is zero (similar to the Laplace kernel) so that the convolution result of homogeneous regions is always zero. Motion filters: Construct an ideal line segment with the length and angle specified by the ar...

Fast 2-D convolution CONVOLVE2 can be used wherever CONV2 is used, taking the same arguments and returning the same results to within a small tolerance. The computation is speeded up by using the singular value decomposition of the mask to express it as a su... D Young 被引量: 0发表:...
Convolution filtering may be expressed as: p x , y ′ = S · ( ∑ i = 0 W - 1 ∑ j = 0 H - 1 k i , j · p x + i - shiftX , y + i - shiftY ) + b , Eq ( 1 ) where W is the width of the grid/kernel and H is the heigh...
