图像增强方法在裂纹骨折判定中的应用

Application of one kind of method in judging the fissurefracture by using image enhancement

目的:提出一种在临床操作使用上更加有效的裂纹骨折判定的图像增强方法,达到清晰判断裂纹骨折的目的。方法:采用5×5模板中值滤波的梯度变换(sobel)图像掩蔽用拉普拉斯变换的图像形成掩蔽图像,并与足部跖骨正位片相加形成锐化图像,再对锐化图像实行对比度自适应直方图均衡化,并比较图像增强前后的效果。结果:采用该算法增强骨折X射线片,能清晰的突出裂纹骨折的形态,所得图像较单独使用一种方法的图像效果更佳。结论:对骨科临床骨折判定有较大价值。

Objective： A more effective approach to judge the fissure fracture by using image enhancement is presented. Methods： The Gradient image after 5×5 median filtering smoothing was used to mask the laplace image, and to add the original image in order to informing the sharpening image, and then the adaptive contrast histogram equalization is put in shaping image and to compare the effect of the image enhancement. Results： The algorithm to enhance the X-Ray fracture image can highlight the shape of the fissure fracture clearly. The enhanced image is more effective than the image by using one way alone. Conclusion： This method is valuable in judging the fissure fracture in clinical diagnosis.
