We propose an information fusion algorithm-common matrix approach-based edge detection-for edge detection in multispectral images based on a tensor projection approach. In order to merge the edge information situated on different spectral bands, the concept of the common matrix approach is enhanced for each band to project a tensor of gradients onto a derived basis. Once a single-gradient map is acquired from the tensor, a smart thinning and thresholding methodology is utilized at the edge extraction stage in terms of getting rid of spots and discontinuous edge pixels. Upon inspecting the experiments' results on datasets including the Computer Vision Laboratory at Columbia University, Scene, scanning electron microscopy using the energy-dispersive x-ray microanalysis, and particular hyperspectral remote sensing datasets, it is observed that the proposed method achieves pleasing results in terms of subjective and objective measures in comparison to some recently proposed edge detectors on multispectral and hyperspectral images.
