结果,该方法保留了边缘,因为对于位于边缘附近的像素,放置在边缘的另一侧上的相邻像素,因此与中心像素相比表现出大的强度变化,将不包括用于模糊。 下面的示例演示了双边过滤的使用(有关参数的详细信息,请参阅OpenCV文档)。 blur = cv2.bilateralFilter(img,9,75,75) 注意表面的纹理(texture)已经模糊掉了,但是边界仍...
Image Processing with OpenCV
while OpenCV handles reading/writing of the image files in this case, but is a lot more capable, providing many advanced graphics procedures—some of which we will use later

Process the image by applying image-processing techniques to achieve the required functionality (for example, detecting a cat in an image). Show the result of the processing step (for example, drawing a bounding box in the image and then saving it to disk). ...
You will then cover all the core image processing algorithms in detail before moving onto the biggest computer vision library: OpenCV. You’ll see the OpenCV algorithms and how to use them for image processing. The next section looks at advanced machine learning and deep learning methods for ...
Image enhancementis a useful pre-processing technique for feature extraction. For WSIs, different contrast enhancement filters can be applied to remove gray areas by using different OpenCV functions like used add Weighted [95] for this purpose. ...
