The ability to use GFP-tagged proteins to perform correlative light and electron microscopy has been a desirable but elusive method. The high quantum yield of GFP that makes it excellent for fluorescence imaging also makes it extremely inefficient for production of the reactive oxygen needed to trigger formation of an electron-dense precipitate for electron microscopy. This roadblock has finall...

We propose a novel, robust scheme for data hiding/ oblivious detection of watermarks in still images. While the low-frequency image coe cients are robust, they cannot be used e ectively for oblivious detection methods, when correlative processing is employed for detection. However, in the proposed non-linear detection method, the robust low-frequency bands can be used e ectively. Thus the propo...

in this paper, an unsupervised method for change detection in the multitemporal multipolarization synthetic aperture radar (sar) imagery is proposed. a matrix distance measure, named symmetric revised wishart is used as a test statistic in order to assess the similarity of two multitemporal multilook polarimetric sar data and a variance-based thresholding algorithm is applied to the test statis...

No-reference image quality assessment aims to predict the visual quality of distorted images without examining the original image as a reference. Most no-reference image quality metrics which have been already proposed are designed for one or a set of predefined specific distortion types and are unlikely to generalize for evaluating images degraded with other types of distortion. There is a str...
