The article proposes two novel and relatively simple unsupervised procedures for the selection of informative small subsets of spectral bands in hyperspectral images. To ensure the informat...

Conditions at which the up-and-down process with a step greater than 0.5 of the standard deviation of masking noise becomes practically closed on a finite set are investigated, e.g., the sufficient number of states of up-and-down process is determine

The paper discusses the properties of a two-stage Bayes classifier construction method in a case when the objects are represented with two quantitative features. The aim of the study was to show that, in general, the two-stage approach allows one to

The paper is focused on problems related to proper selection of relatively small number of bands from hyperspectral images ensuring sufficiently accurate classification of pixels into several defined categories. Two approaches to construction of the

Finitely generated bi-ideals with letters from a selected alphabet A are considered. We solve the equivalence problem for generating systems of bi-ideals, i.e., look for an effective procedure which provides the means of determining if two generating
