为了提取颜色,我们有这个功能

# define range of blue color in HSV
lower_blue = np.array([110,50,50])
upper_blue = np.array([130,255,255])

# Threshold the HSV image to get only blue colors
mask = cv2.inRange(hsv, lower_blue, upper_blue)

我们如何实际可视化我在hsv空间定义的范围(lower_blue,upper_blue)？另外我如何实际绘制hsv颜色,但它不起作用......？我有这个代码:

upper = np.array([60, 255, 255])
upper = cv2.cvtColor(upper, cv2.COLOR_HSV2BGR)


upper = totuple(upper/-255)
print(upper)
plt.imshow([[upper]])
