This line declares a 2D vector named "contours", where each element of the vector is itself a vector of points. This data structure is commonly used in computer vision and image processing to store the contours or boundaries of objects detected in an image. The outer vector can store multiple contours, while the inner vector contains the set of points that make up each individual contour.
