Now, click on the red shade that you copied. WebThe syntax to define HSV range in OpenCV is as follows: hsvcolorspace = cv.cvtColor (image, cv.COLOR_BGR2HSV) lower_hsvcolorspace = np.array ( [Hue range, Saturation range, Value range]) upper_hsvcolorspace = np.array ( [Hue range, Saturation range, Value range]) where hsvcolorspace is the conversion of the given image in RGB format to HSV This roomy but small Spa is packed with all the features of a full 11-13/16 square and the depth!
