Line detection Fusion using Spatial Frequency Measurement

In this paper, we present a line detection fusion method using Spatial Frequency Measurement (SFM). Our proposed method, A¿ trous algorithm is firstly applied with the original image to get the line feature detail information in two difference resolutions from a coarse one with 5×5 mask and a fine one with 3×3 mask. Next, both line feature detail information are fused to get a complete line feature using Spatial Frequency Measurement, which is compared with Laplacian Operator. From the experiments, we found that our proposed method provides a complete line feature evaluated by the correlation value. Also, the method is general and can be applied to other features in imagery.
