Complex Color Space Segmentation to Classify Objects in Urban Environments

open access: yesMathematics, 2022
Color image segmentation divides the image into areas that represent different objects and focus points. One of the biggest problems in color image segmentation is the lack of homogeneity in the color of real urban images, which generates areas of over ...

Topology and Metricity of the Complex Plane

open access: yesDavao Research Journal, 2002
The equinumerosity of the set of complex numbers and a set of ordered pairs of real numbers is used to show the topology of the complex plane. Likewise, the metricity of the complex plane is proved with the aid of the metricity of the plane R.

Convert between neutrosophic complex numbers forms [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
Complex numbers have been studied in previous papers, but the papers did not deal with the conversion from algebraic form of a neutrosophic complex number form to exponential or trigonometric form and vice versa, and this prompted us to search for a ...
