In salient lines matching, affine invariants are calculated and the matched salient line correspondences are the basis of the general lines matching. Each general line is clustered into a matched salient line according to a certain rule. Taking each salient line as the root, together with all ...
A third one may appear under special conditions.It passes through singular points B: (−1a , 0) and C: (0,λd ), as it could not cross the axes elsewhere, therefore, the equation of this line is dy −λax−λ = 0. Invariance of this line implies the integrability of 系统总...
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...

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...
Cell and organelle shape are driven by diverse genetic and environmental factors and thus accurate quantification of cellular morphology is essential to experimental cell biology. Autoencoders are a popular tool for unsupervised biological image analysis
Invariant skew-symmetric differential operators on the line and Verma modules over the Virasoro algebra It turns out that the problem of enumeration of the invariant skew-symmetric differential operators of the line is closely connected with the problem of reducibility of the Verma modulus over a ...
Using the Hough Transform we extract shape signatures that correspond to important features of an image. The new shape descriptor is robust against line discontinuities and takes into consideration not only the shape boundaries, but also the content inside the object perimeter. The object signatures ...
