摘要：

Advances in digital chest and breast radiography require optimal image processing techniques. We present a new algorithm to enhance the edges and contrast of chest and breast radiographs while minimally amplifying image noise which consists of a linear combination of an original image and two smoothed images obtained from it using differents masks and parameters, followed by the application of a nonlinear contrast stretching. The result is an image which retains the high median frequency local variations (edge and contrast-enhancing).
