These technologies can involve new types of sensors, as in remote sensing, but also mathematical models leading to an increased cardinality at each pixel. This work analyzes the role of first-order differentiation in vector-valued images; specifically, we explore a novel operator to produce a 2D vector from a Jacobian matrix, in order to represent the variation in a vector-valued image as a planar feature.engbook parthttps//doi.org/10.1007/978-3-319-66824-6 38https://link.springer.com/chapter/10.1007/978-3-319-66824-6_38restricted access510.6Vector-valued imagesDifferentiationJacobian matrixInformation fusionLógica simbólica y matemática (Matemáticas)1102.14 Lógica Simbólica
