Intelligent Detection Method for Internal Cracks in Aircraft Landing Gear Images under Multimedia Processing

In view of the lack image enhancement processing in traditional methods preprocessing, which leads to a long detection time for internal cracks and poor visual effects, an intelligent method aircraft landing gear images under multimedia is proposed. A spatial index structure established based on database, are enhanced denoised. Image segmentation performed according preprocessing results, crack foreground road surface background separated, threshold value each calculated. The result used distinguish pixels areas where may exist belong background, judgment realizes detection. experimental results show that proposed shorter, effect better, average expert score reaches 93.6 points, verifies effectiveness from both subjective objective aspects.
