ABSTRACT
The purpose of this thesis is to show that isolated pixel filtering-based image inpainting methods for drawing robots. For watercolor painting, HSI color space is used to improve the effect of color simplification such that the recognition of image processing results is enhanced, firstly. Second, that less-affected isolated point color is replaced with the surrounding color via isolated pixel filtering methods. Third, we use image inpainting technology to reduce the distortion caused by the isolated pixel filtering. Besides, we adjusted the path planning as well as reduced isolated points to dramatically reduce drawing time. For sketch painting, through the image resolution adjustment as well as the shortening of the spacing of the drawing lines, the robot can draw more detailed pictures in the same size of drawing space. To allow LabVIEW to directly issue commands to control the drawing robot, the communication function has been added. The measured results confirm that the application of the technology in this paper can shorten the drawing time by about 57% to 59% on the drawing robot system.
