混合滤波器在血管造影图像处理中的应用

Application of hybrid filters in angiogram image processing

为了提高血管造影图像的清晰度 ,提高在医学诊断中的精确性 ,采用混合滤波手段。首先采用均值滤波器对原始图像滤波、然后通过改进的拉普拉斯锐化滤波器对图像进行处理 ,并结合其它图像处理手段对滤波结果进行后处理。最终图像消除了血管造影图像的模糊现象 。

In order to improve the clarity of angiogram images and the precision of diagnosis,hybrid filters are used to process the images. The original image is first processed with the average filter and the Laplacian operator,then the obtained image is further processed with the histogram equalization method. Experimental result shows that the phenomenon of blur disappeared on the final image and the angiogram reflected the fact more effectively.
