How to use?
from magic_bbox import Magic_Bbox import numpy as np import cv2 if __name__ == "__main__": img = np.zeros((320, 320, 3), np.uint8) # 生成一个空灰度图像 bbox = (60, 60, 260, 260) color = (255,255,0) ''' type: 0 | 1 | 2 ''' mb = Magic_Bbox(color=color) img = mb.draw(img, bbox, '1') mb.show(img)
完毕!
