The problem of identifying spatial objects in images at various scales and at specified intervals is considered. The algorithm makes comparison on the basis of topological features, in this case using threedimensional barcodes based on persistent homology methods. The result of the algorithm is the identification of objects in images for different time intervals and at different scales, based on the obtained threedimensional barcodes. The analysis of various approaches to the search for spatial objects in satellite images is carried out, the advantages and disadvantages are identified. In the work, pictures of water bodies for different years and at different scales were investigated. Charts of three-dimensional barcodes for these objects which reflect the similarities and differences in the structure of objects are constructed.
Key words: three-dimensional barcode, persistent homology, topology, spatial objects.
