OpenCV có giao diện Python mà bạn có thể xem. Nếu các ký tự, không thay đổi quá nhiều, bạn có thể thử sử dụng hàm matchTemplate.. Here là hướng dẫn chính thức về nó (hướng dẫn được viết bằng giao diện C++, nhưng bạn sẽ có thể có ý tưởng tốt về cách sử dụng hàm trong Python từ nó).
Začiatočník v OpenCV a každá nápoveda sa cení. Podľa dokumentácie imfill v MATLABe: BW2 = imfill(BW,'holes'); vypĺňa otvory v binárnom obraze BW. Diera je sada pixelov pozadia, na ktorú nie je možné dosiahnuť vyplnením pozadia od okraja obrázka. OpenCV (canny edge detection)의 가장자리 감지 모듈에서 추출한 가장자리지도가 있습니다. 내가하고 싶은 것은 가장자리지도의 구멍을 채우는 것입니다. 나는 C ++ 과 OpenCV 라이브러리를 사용하고있다.

The Idea : Template Matching is a method for searching and finding the location of a template image in a larger image. We’ll also be using scikit-image instead of OpenCV, mainly because we’ll also be using dlib which is built to play nice with scikit-image .

Looking at our argument parsing section, you’ll notice that we need 3 switches: –class : This is the path to our specific CALTECH-101 class that we want to train an object detector for. 开运算是对图像腐蚀和膨胀的组合，OpenCV 4没有提供只用于图像开运算的函数，而是提供了图像腐蚀和膨胀运算不同组合形式的**morphologyEx()**函数，以实现图像的开运算、闭运算、形态学提取、顶帽运算、黑帽运算以及击中击不中变换，该函数的函数原型在代码清单6-15中给出。 I am trying to implement template matching for multiple objects using C++, but I am unsure how to implement the example given in the documentation in C++. I have looked online for solutions, but none seem to approach it the same way the documentation does.

| PixelSquid I'm starting on OpenCV again after I've tried it in Android some time ago. Now, I'm trying OpenCV 2 with Python 2. So far, I've been able to use it to get the live camera feed, and on a separate project, I've been able to implement template matching where I'll give a parent image and a small image that exists in the parent image, and match the sub images in the parent image and then output The Professional Numismatists Guild (PNG) is a nonprofit organization composed of many of the country's top rare coin and paper money experts who undergo a background check, must adhere to a strict code of ethics in the buying and selling of numismatic items and who guarantee the authenticity of the numismatic merchandise they sell. Template Matching is a method for searching and finding the location of a template image in a larger image. OpenCV comes with a function cv.matchTemplate() for this purpose. It simply slides the template image over the input image (as in 2D convolution) and compares the template and patch of input I have an edge map extracted from edge detection module in OpenCV (canny edge detection).

In OpenCV there is a cvFloodFill() function, and it will fill the holes with a seed (with one of the location to start flooding). However, I am trying to fill all the interior holes without knowing the seeds.(similar to imfill() in MATLAB) 开运算是对图像腐蚀和膨胀的组合，OpenCV 4没有提供只用于图像开运算的函数，而是提供了图像腐蚀和膨胀运算不同组合形式的**morphologyEx()**函数，以实现图像的开运算、闭运算、形态学提取、顶帽运算、黑帽运算以及击中击不中变换，该函数的函数原型在代码清单6-15中给出。 of the coins.
