METHOD OF DETERMINING HIGHLY INFORMATIVE SEGMENTS OF AERIAL PHOTOGRAPH

Abstract

A variant of solving the problem of reducing the informative intensity of the video stream coming from the aircraft without loss of its efficiency and reliability is discussed. The analysis of aerial photographs, which constitute informative redundancy and subsequently complicate the process of its interpretation is made. The implementation of decryption coding technology for aerial photography is disclosed. A model for the classification of informative segments of an aerial photograph is considered. The direction of reducing the information redundancy of aerial photographs with preservation of key information to its interpretation is proposed. The substantiation of a method of exact allocation of highly informative segments from the whole aerial photograph, which carry the maximum information objects in the interests of interpretation is given. A technological concept of an effective syntactic description of the elements of sufficiently informative segments of an aerial photo is taken into account, which takes into account the characteristics of the transformant components of the discrete cosine transform. Moreover, such a concept is aimed at maximum preservation of key information to decipher the whole aerial photo. A method is constructed for accurately isolating highly informative segments from the entire aerial photograph, which carry the maximum information objects in the interest of deciphering. This will allow to allocate and completely transfer not distorted key information to the deciphering of the whole aerial photo. That, in turn, will shorten the time and increase the probability of correct interpretation. A promising technological concept of an effective syntactic description of the elements of sufficiently informative segments of an aerial photograph that takes into account the characteristics of the DCT transformant components. The scheme for evaluating the significance of transformants of an aerial photograph informative segments is considered. It is substantiated that the proposed version will provide simultaneous reduction of the information necessary for presentation of service data and will create prerequisites for effective reduction of informative intensity of the whole segment of the aerial reconnaissance
