Gray-scale Image Edge Detection Based on directional Beamlet Transform

摘要：

Traditional edge detectors based on pixel processing one by one have poor ability to detect edge in noisy images.The beamlet transform is a method of linear feature detection but fail to detect edge.The directional beamlet transform is proposed in this paper.The DBT transfer the linear singularity to point-singularity,and reduce the influence to edge of noise.Experiment results prove the efficiency of the method proposed even in noisy images.
