1 dzień temu · 0. I have a circle "map", which is basically an np.array() of coordinates which represent a circle with a fixed radius. I also have another np.array: screen=np.ones((dimensions of the screen), dtype=np.uint8). This is essentially a black canvas. I have a two dimensional numpy array: myarray=[[0,0],[1,1],[2,2]] I also have a grid of points ...
What are contours? Contours can be explained simply as a curve joining all the continuous points (along the boundary), having same color or intensity. The contours are a useful tool for shape analysis and object detection and recognition. For better accuracy, use binary images. So before finding contours, apply threshold or canny edge detection.
