Unsupervised depth completion aims to recover dense from the sparse one without using ground-truth annotation. Although measurement obtained LiDAR is usually sparse, it contains valid and real distance information, i.e., scale-consistent absolute values. Meanwhile, scale-agnostic counterparts seek estimate relative have achieved impressive performance. To leverage both inherent characteristics,...

In this manuscript, if a reduced divisor D0 of hyperelliptic curve of genus g over an extension field Fqn is written by a linear sum of ng elements of Fqn -rational points of the hyperelliptic curve whose x-coordinates are in the base field Fq, D0 is noted by a decomposed divisor and the set of such Fqn -rational points is noted by the decomposed factor of D0. We propose an algorithm which chec...

We study the solution of the discrete logarithm problem for the Jacobian of a curve of genus g defined over an extension field Fqn , by decomposed attack, considering a external elements B0 given by points of the curve whose x-coordinates are defined in Fq. In the decomposed attack, an element of the group which is written by a sum of some elements of external elements is called (potentially) d...
