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...

Wavelets and multi-resolution processing: This is the foundation of representing images in various degrees. Image compression: Image compression works on the image size and its resolution. It can be done easily with OpenCV's cv2.resize(image, (new_width, new_height)) function. Morphological proc...
Image processing is done in software by applying numerical operations on the image data. Most common image processing techniques have a solid mathematical background. What is Python, NumPy and OpenCV? Python is a programming language well suited for scientific computing. NumPy is a Python library ...
