Ultrathin polymer monolayers for promotion of cell growth on bioprosthetic materials -- evolution of a new concept to improve long term performance of biologic heart vales.

abstract：:To better analyze images with the Gaussian white noise, it is necessary to remove the noise before image processing. In this paper, we propose a self-adaptive image denoising method based on bidimensional empirical mode decomposition (BEMD). Firstly, normal probability plot confirms that 2D-IMF of Gaussian white noise...
