Result:
I have used face++ api to detect the landmark feature and use the point to enclosed an area but I hope to fill the enclosed area of the upper and lower lips. How can I do this in android? The above is the code that I enclose the area. Please give me some helps to fill the upper and lower lips.
Also, one more question. May I use HSV color space to set the color of the paint instead of using RGB and may I only change the H value of each pixel so that it will not change the brightness of the image? Thank you very much.
