In digital image processing, image enhancement is employed to give a better look to an image. Color is one of the best ways to visually enhance an image. Pseudo-color refers to coloring an image by mapping gray scale values to a three dimensional color space. In this paper we used a ...
Image decomposition in frequency domainImage fusionDual optical pathIn this paper, we propose a novel molten image enhancement and fusion method based on image decomposition in frequency domain. The algorithm combines the guided filter to maintain the original edge and details and to make it show a...

This paper shows how the directional image enhancement can also be done in the frequency domain. This approach overcomes the noise and high-curvature limitation of the spatial domain methods. 展开 关键词: Fingerprint recognition Image enhancement ...
Image enhancement is one of the types of processing in digital image processing domain. To perform this operation sophisticated wavelet transformation is used which has better enhancement as compared to their spatial domain counterpart. In ...
