    The goal of presented work was to verify that image signatures can be used in rough selection of the aerial subimages. The selection process is necessary to determine if the aerial image is suitable for next stages of photogrammetric processing, especially for matching. More than 900 image signatures (of length 25 and 50) was generated by the ICM network. The backpropagation network was used for classification. After learning the recognition rate of the test set was 73%. As the next step three recognition reliability thresholds was tested. After data rejection both recognition reliabilities and recognition rates were improved (?80%).
