Joint MRI Bias Removal Using Entropy Minimization Across Images
The correction of bias in magnetic resonance images is an important problem in medical image processing. Most previous approaches have used a maximum likelihood method to increase the likelihood of the pixels in a single image by adaptively estimating a correction to the unknown image bias field. The pixel likelihoods are defined either in terms of a pre-existing tissue model, or non-parametric...
متن کاملIntrinsic Images for Shadow Removal
The purpose of this report is to summarize the work done by a number of researchers over the course of a number of years related to creating illumination invariant images for the purpose of shadow removal. We will also discuss the experiments that were implemented in order to test the algorithm on consumer-grade digital cameras, and the results of these experiments.
متن کاملSimple Shadow Removal
Given the location of shadows, how can we obtain highquality shadow-free images? Several methods have been proposed so far, but they either introduce artifacts or can be difficult to implement. We propose here a simple method that results in virtually error and shadow-free images in a very short time. Our approach is based on the insight that shadow regions differ from their shadow-free counter...
متن کاملPath-Based Shadow Removal
In the path based method, an error made at a time t1 is propagated throughout all t ≥ t1. We make the framework robust by addressing causes for errors and artifacts. • “Open” Shadow Masks: Wrong information propagated •Too many crossings of the shadow edge: sensitive to noise and material changes •Too regular paths: Easily visible artifacts •Sensitive information “under” shadow edges: reintegra...
متن کاملTexture-Consistent Shadow Removal
This paper presents an approach to shadow removal that preserves texture consistency between the original shadow and lit area. Illumination reduction in the shadow area not only darkens that area, but also changes the texture characteristics there. We achieve textureconsistent shadow removal by constructing a shadow-free and textureconsistent gradient field. First, we estimate an illumination c...
