The level set approach is a powerful tool for segmenting images. This paper proposes a method for segmenting brain tumor images from MR images. A new signed pressure function (SPF) that can efficiently stop the contours at weak or blurred edges is introduced. The local statistics of the different objects present in the MR images were calculated. Using local(More)
This paper proposes a new method for information hiding based on secret fragment visible mosaic image. This algorithm incorporates the application of color transfer for the mosaic image generation to hide the secret information. Since the RGB color space has strong correlation between three color channels, the modification process of any color is(More)
