Abstract:
A method for adaptive recognition of information images, comprising steps of:processing each input information image in accordance with a recognition algorithm; comparing the input information image being processed with a model image in order to estimate discrepancies between the compared images; comparing at least one estimate of the obtained discrepancies with at least one predetermined threshold; when said estimates exceed the predetermined thresholds, correcting the recognition algorithm, and repeating the previous operations using said recognition algorithm for the same input information image, wherein said method further comprising steps of: forming models of probable information images; for the probable information images, creating the recognizing algorithms based on the formed models; processing the information image in accordance with one of the created recognition algorithms; performing, after said processing step, a model recovering of the processed information image in accordance with the recovery algorithm which is inverse of the utilized recognition algorithm; the step of comparing the input information image being processed is performed with the recovered model image, calculating coincidence estimates, and then performing said step of comparing the estimates with the predetermined thresholds; when the predetermined number of estimates do not exceed the predetermined thresholds, deciding on the recognition of the input information image; correcting the recognition algorithm when the predetermined number of estimates exceed the predetermined thresholds, and then repeating, using the corrected algorithm for the same input information image, the steps of processing the information image, recovering the model image, comparing those images, and comparing the obtained estimates; repeating the previous step until deciding on the recognition of the input information image, or deciding on the absence of possibility for recognizing this image on the basis of an available set of algorithms.
