Hierarchical image segmentation to infrared images
Bloomquist, James D.
MetadataShow full item record
Becursive image segmentation with hierarchical scope views is a new technigue in image processing which systematically divides an image into smaller and smaller quadrants with each region within the quadrants having a structured descriptor. The regions are then processed to remove noise and to check for connected regions across the guadrant boundaries. The quadrants are then brought back together with the obscured target enhanced and distinguishable from the background. Infared image data of five different ship targets with the associated noise and inteference was processed by this technique with the target information being greatly enhanced. The procedures developed to evaluate the data were found to be inadequate for the task, neccessitating hand evaluation to extract the target. Ihe technique was proven to be a viable solution for extracting target information from infared data, but very slow processing times and inadequate evaluation procedures limit the usefulness of the program in its present form.
