تطوير مرشحات رقمية لإزالة الضوضاء الكاوسية لصور طبية

Abstract

The noise accompanying the pictures medical Among the problems faced by the process of diagnosing diseases by these images, as well as the lack of image quality due to lighting and contrast wanted, because it makes the process of interpretation and analysis of medical images resulting from a difficult process, it was in this research using the equations of innovative composite functions, hyperbolic and exponential function was compensation for the value of the variable values for these equations radial angles and after extraction output each angle were compensated output in the matrix dimensions (7 * 7), including our digital filters to remove the Gaussian noise accompanying medical images taken by different techniques
