Segmentation of Nanocolumnar Crystals from Microscopic Imagesany applications whose interest has been growing recently. One of these applications are light-collecting devices such as solar cells, using nanostructured substrates. Electrodeposition is a low cost technique very suitable for the preparation of nanostructured ZnO, producing nanocolumnar ZnO crysta

Mutual Information-Based Methods to Improve Local Region-of-Interest Image Registrationeir region of overlap. In applications such as planned radiation therapy, a diagnostician is more concerned with registration over specific regions of interest (ROI) than registration of the global image space. Registration of the ROI can be unreliable because the typically small regions have limite

Image Denoising Using Complex Wavelets and Markov Prior Models complex wavelet transform outperforms the standard real wavelet transform in the sense of shift-invariance, directionality and complexity. The prior MRF model is used to exploit the clustering property of the wavelet transform, which can effectively remove annoying pointlike artifacts associated wi

Image Denoising Using Neighbor and Level Dependencyen neighboring wavelet coefficients and their corresponding coefficients in the parent level. We also investigate a multiplying factor for the universal threshold in order to obtain better denoising results. An empirical study of this factor shows that its optimum value is approximately the same for

Shadow Removal in Gradient Domainny assumptions. In this paper, we suppose that the texture beneath shadow should bear the similar patterns, which makes the problem of simultaneously recovering the reflectance and light attenuation factor solvable with sole image. A novel shadow removal method is proposed, which is fulfilled by com
