INTRODUCING THE WEIGHT CONCEPT TO VECTOR DIRECTIONAL FILTERS

Rastislav Lukáč

   In color images and satellite images, each image point can be represented as a vector of R, G, B components. The filtering of these vector-valued image signals is constrained by the requirement for the preservation of all desired image features, including color information. On that account, vector techniques such as vector median-type filters based on a reduced ordering scheme according to the absolute or Euclidean distance and vector directional filters based on the vector angle distance were developed.

Keywords: directional filters, vector filters, weighted directional filters, angle distance
