摘要:The concept of the research was based on the selection of several representations, which were later correlated by means of conventional,and neural methods. In the course of research, conventional methods of image matching were tested and compared with neural methods that originating from the research process. Additionally,experiments consisting in manual measurements, performed by independent observers,were conducted.The essence of methodology that was based on neural networks consisted in the preparation of suitable representations of image fragments and using them for the classification of various types of neural networks. One of the assumed methods was based on the distribution of image gradient module value and of its direction. The usability of that representation for the selection of sub-images was tested by means of SOM Kohonen neural network. Another method consisted in the utilisation of the log-polar and log-Hough transforms,which are considered to be simplified models of preliminary image processing,performed by visual systems of people and animals. The usability of that representation was tested by means of the backpropagation type of neural network. As regards the generation of the third representation,the ICM (Intersecting Cortical Model) network was applied, which is one of the versions of the PCNN (Pulse Coupled Neural Network). Using that network,the so-called image signatures,or vectors composed of tens of elements which describe the image structure,were generated.
其他摘要:Koncepcja opisywanych badań opierała się na wyborze kilku reprezentacji,które następnie korelowano przy pomocy metod klasycznych i neuronowych. W trakcie badań przetestowano metody klasyczne spasowania obrazów i porównano je z powstałymi w trakcie badań m
