A Method of Image Transform Based on Linear Elements

The influence of noises is obviously in the image transform method based on the pixels elements representation of images. To some extent the method of image transform based on linear elements representation can solution the problem. The Beamlet transform is an effective method of line segment extraction. This work improved the traditional Beamlet transform by considering the directional information of lines. The improved method transformed a digital image to a coefficient matrix. This method can embody the linear singularity of some linear targets and can be used for edge detection and extracting other useful targets in noisy images. The experimental results on manual images and SAR images demonstrate the effectiveness of this method.
