| 摘 要： | 采用组合方法对图像进行增强,对原始图像进行双平台直方图均衡,对均衡后的图像灰度进行等间距处理,提高整体图像的对比度;采用中值滤波方法对原始图像进行滤波,再用Sobel边缘微分算子对滤波后的图像进行边缘提取.在双平台直方图均衡后的图像中,对边缘所对应的像素的灰度值进行处理,对非边缘所对应的像素保持原灰度值不变,然后将处理后的边缘像素与不处理的非边缘像素进行组合.

| Abstract: | Image is enhanced using combination methods.Dual-platform threshold is selected for balancing the current histogram of the infrared image to enhance the overall image contrast;median filtering method is used for remove the pulse noise of the original image,and then edge is detected with Sobel edge differential operator;gray value of the edge g pixel corresponding in the histogram equalization image is processed,gray value of non-edge pixels corresponding remains unchanged,and finally pixel of the edge proce... |
