Q: Why the package and import are different (opencv-python vs. cv2)? A: It's easier for users to understand opencv-python than cv2 and it makes it easier to find the package with search engines. cv2 (old interface in old OpenCV versions was named as cv) is the name that OpenCV developers chose when they created the binding generators. This is ...

How to split the color channels of an image, using Python and OpenCV. This tutorial was tested on Windows 8.1, using Python version 3.7.2 and OpenCV version 4.1.2.
Although the library provides a Java interface (OpenCV4Android) and a Python interface as well, most parts of these interfaces are thin layers atop the C++ implementation. For example, an org.opencv.core.Mat object (in the Java interface) or a NumPy array (in the Python interface) is backed by a cv::Mat object (in the C++ implementation), and ...

Jul 15, 2011 · One happy side effect of the new (> v2.1) python-opencv bindings is that they do no validation on CvImage.SetData, which means you can pass an arbitrary string/pointer. Because of this I advised him I thought using something like SWIG was overkill, and he could just write a wrapper to his library using ctypes, or a thin python extension directly.

Edge detection is an image processing technique for finding the boundaries of objects within images. It works by detecting discontinuities in brightness. Edge detection is used for image segmentation and data extraction in areas such as image processing, computer vision, and machine vision.
Actually, I only found one for OpenCV, a seven part tutorial by Pierre Raufast, the guy behind Magic Mirror project. The idea of this tutorial is to modify source code of raspivid and raspistill to use buffer memory of the camera to feed OpenCV image objects. This was a great step in making it work, but not an easy one, everyone can follow.
Tramite OpenCV viene catturato lo stream video della camera IP, l'immagine viene elaborato alla ricerca del colore verde calcolando il centroide, a questo punto si calcola la posizione del centroide rispetto al centro dell'immagine e si pilota la camera per posizionare il centroide piu' vicino possibile al centro dell'immagine.
Thinning is the dual of thickening, i.e. thickening the foreground is equivalent to thinning the background. Guidelines for Use One of the most common uses of thinning is to reduce the thresholded output of an edge detector such as the Sobel operator , to lines of a single pixel thickness, while preserving the full length of those lines ( i.e ...
