Fusion of WorldView2 images using Contourlet, Curvelet and Ridgelet transforms for edge enhancement

Abstract: This article discusses the implementation of three transforms, namely Contourlet, Curvelet and Ridgelet, which are intended for image edge enhancement. These transforms were applied to fused Worldview 2 satellite images. The fusion was performed over the WorldView 2 satellite images applying various types of wavelet transforms, such as Daubechies, Bior, rbior, Coiflet and Symlet 5, with different levels of decomposition. The best results were obtained for the case of Symlet 5, level 5. Wavelet fused images and… Show more

“…The CoT offers a flexible multiresolution and directional decomposition for images as it allows for a different number of directions at each scale [15]. This transform improves the contours or provides a smooth representation of such contours using fewer coefficients than those required by Wavelets [16].…”
