In image processing, considering fields like remote sensing and medical applications, Speckle (Multiplicative) noise dominates which affects the valuable features and important information of the image. To denoise an image, various transforms are used. But they are not efficient in case of preserving the edges which is the important factor in image(More)
Aglaia roxburghiana is a traditional remedy for a variety of diseases. The ethanolic extract of the leaves was screened for related activities were upon it exhibited significant anti-inflammatory activity in rats in acute and chronic models. There was no acute toxicity in mice upto 2g/kg. The extract protected the mast cell deregulation by compound 48/80(More)
The alcoholic extracts of the aerial portion and fruits of Aglaia roxburghiana (W.& A.) Miq. var. beddomei and the triterpenes roxburghiadiol A and B isolated from this plant were investigated for their anti-inflammatory activity in rats by carrageenin induced rat paw oedema and cotton pellet granuloma methods. They were also studied for their effect on(More)
Heterocysts isolated from Anabaena variabilis incorporate [14C]leucine and [35S]methionine into trichloroacetic acid-precipitable material in the light. Analysis by polyacrylamide gel electrophoresis shows that the radioactivity is present in polypeptides of discrete sizes. However, the relative proportions of different proteins synthesized by isolated(More)
In this paper, we developed an algorithm to remove additive mixed noise in images with the preservation of fine details and edges. The noise characteristics may vary in the same application from one image to another. In these environments, nonlinear general filters will not perform well and adaptive non-linear filters are best suited. The algorithm based on(More)
