摘　　要：使用Laplacian算子检测图像的边缘纹理等细节信息,然后以适当比例线性叠加原始图像和细节信息,从而完成图像增强。不同增强方法的比较试验表明,基于Laplacian算子的图像增强方法既能增强图像的高频分量,又能保持图像的低频分量,是图像增强的有效方法。Laplacian operator is used to detect the fine detail of image such as edge and texture, and image was enhanced by linear combination of original image and its fine detail in some proportion. Various enhancement methods are given. Results show that the method based on Laplacian operator not only enhances the high-frequency component but also keeps the low-frequency component, therefore it is an efficient method of image enhancement.
