PROBLEMS OF SPATIAL IMAGES PROCESSING AND SOME APPROACHES TO THEIR SOLUTION
The basic problems constraining the development of spatial images processing methods based on the theory of signals are formulated. Approaches to solving the tasks lowering the complexity of some of such problems are considered. These tasks are as follows: ordering of the points of the spatial group dotted object, allowing to lower the space dimension; formation of a measure of similarity of the volumetric images set by quaternion signals; defining of a subspace in which operation of multiplication of quaternion signals becomes commutative.
