May 2, 2012 · Officially, OpenCV releases two types of Python interfaces, cv and cv2. cv: I started working on cv. In this, all OpenCV data types are preserved as such. For example, when loaded, images are of format cvMat, same as in C++. For array operations, there are several functions like cvSet2D, cvGet2D, etc. And some discussions say, they are slower.

queryDescriptors (cv2.typing.MatLike) – masks (_typing.Sequence[cv2.typing.MatLike] | None) – Return type: _typing.Sequence. match (queryDescriptors, trainDescriptors [, mask]) → matches ¶ Finds the best match for each descriptor from a query set.

These examples, written in Python, will provide a good starting point for a lot, and the most common, applications of GStreamer and OpenCV. The snippets mainly use OpenCV's VideoWriter and VideoCapture object, and include the following functionalities:

cv2.ellipse(img, center, axes, angle, startAngle, endAngle, color[, thickness[, lineType[, shift]]]) → img Parameters • img – image • center – • axes – • angle – • startAngle – • endAngle – • color – • thickness – -1 Sample Code img=cv2.ellipse(img, (256,256), (100,50),0,0,180,255,-1) 3.6Polygon
