这里就有点疑惑了,这个式子说明k=8的时候y=-2x上的点全都会被矩阵变成(0,0),倒是也满足y=-2x,可是这已经不能叫“invariant line”(重点是line)了,因为整条线都变成一个点了,而不是像m=4的时候一样变完了还是一条线: 所以,这个时候实际上只有一条invariant line y=4x。 k≠8的原因知道了,可是做题的时候怎么能想到这

●英文摘要 In this work, we investigate the coregistration of multimodal data, such as photogrammetric/LiDAR point clouds, digital surface models, orthoimages, or 3D CAD city models, using corresponding line segments. The lines are analytically derived as intersections of adjacent planar surfaces, whi...

Strain in an infinitesimal line element. (2.37)εxx=dudx. Similarly, in other directions: (2.38)εyy=dvdy, (2.39)εzz=dwdz, where u, v, w are the displacements along the x, y, and z axes, respectively. We can find complete 2D relations between strain and displacement by considering...
1c shows that applying a standard neural networks architecture to the invariant curves in (b) can accurately classify points according to the line from which they originated. The other rows show that when the intrinsic dimension of the data is increased, more invariant features are needed, where...
Origami offers an avenue to program three-dimensional shapes via scale-independent and non-destructive fabrication. While such programming has focused on the geometry of a tessellation in a single transient state, here we provide a complete description o
A novel on-line video object segmentation scheme based on illumination-invariant color-texture feature extraction and marker prediction is proposed in this paper. First, the location of the object of interest is initialized based on user-specified markers. Superpixels are generated in the next availab...
