A method of storing and retrieving images of people, for example, in photographic archives and for the construction of identikit images

摘要

Each characteristic (or feature) of the images to be stored is associated with a region (r_F) the size of which corresponds to the average size of the feature in the images stored. If {F_¡}_{¡ = 1, ..., N} is a set of images of the feature F, where F_i is the image associated with each of the N people in the data base, on the basis of these images, a new set of images {Φ_j}_{j=0, 1, ..., N} of the type ${\mathrm{F}}_{\mathrm{i}}={\displaystyle \sum _{\mathrm{j}=\mathrm{1}}^{\mathrm{N}}}{\mathrm{C}}_{\mathrm{Fij}}{\mathrm{\Phi }}_{\mathrm{j}}+{\mathrm{\Phi }}_{\mathrm{o}}\mathop{\mathrm{image}}$ is generated, of which a subset {Φ}_{i=0, ..., K} can be used to approximate, encode, compare and construct images of the type in question in an interactive manner.;The preferred application is in techniques for searching photographic archives and for the construction of identikit images.
