Identification of Lines Based on Form Factor and Geometrical Descriptors

The problems of releasing and identifying features key elements their identification in images are shown. basic algorithms methods for forming descriptors the image considered. main disadvantages existing aerospace loss stability presence a large number false when changing recording to theconditions (for example, brightness contrast received images). To eliminate these drawbacks, it is proposed use selected lines as elements, geometrical characteristics form descriptor. analyze algorithm andthe SIFT method, fragments changed graphic editor from -50 +50 percent original were used, which made possible evaluate operation conditions close real survey. It shown that more stable than method with increasing decreasing test image. Also, characterized by smaller detected compared method.
