Ross,&#8221; Aniruddha Singhal, one of the researchers who carried out the study, told TechXplore. &#8220;I connected it with another book that I had read earlier, titled &#8216;In Pursuit of the <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/trip-and-travel\/\" data-internallinksmanager029f6b8e52c=\"10\" title=\"Trip &amp; Travel\" target=\"_blank\" rel=\"noopener\">Travel<\/a>ling Salesman&#8217; by William J. Cook, discussing traveling salesman problem (TSP) art. I realized I could also interpret the article from a Vedantic (Indic or Hindu philosophical) point of view, which connects the idea of TSP art and the Jordan curve, turning it into an expression of the ultimate beauty.&#8221;<\/p>\n<p>A Jordan curve is essentially a single line that starts and ends in the same point in space, drawing an image without ever intersecting itself. TSP art, on the other hand, is a form of art in which images are produced by drawing a single, non-intersecting line.<\/p>\n<figure class=\"mb-4\" itemscope=\"\" itemtype=\"http:\/\/schema.org\/VideoObject\"><meta itemprop=\"name\" content=\"Chitrakar: A system that can transform images of human faces into drawings\"\/><meta itemprop=\"url\" content=\"https:\/\/www.youtube.com\/watch\/?v=Yj-jLHGbVXI\"\/><meta itemprop=\"description\" content=\"Chitrakar: A system that can transform images of human faces into drawings\"\/><meta itemprop=\"uploadDate\" content=\"2021-01-05T03:58:13-05:00\"\/><meta itemprop=\"embedUrl\" content=\"https:\/\/www.youtube.com\/embed\/Yj-jLHGbVXI\"\/><meta itemprop=\"thumbnailUrl\" content=\"https:\/\/img.youtube.com\/vi\/Yj-jLHGbVXI\/maxresdefault.jpg\"\/><br \/>\n             <iframe loading=\"lazy\" title=\"Chitrakar: Robotic System for Drawing Jordan Curve of Facial Portraits\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/Yj-jLHGbVXI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<\/figure>\n<p>After reading about Jordan curves and TSP art, Singhal, who is a roboticist, started investigating the possibility of automatically producing TSP drawings, which are very difficult for humans to create. In collaboration with his colleagues at the TCS Robotics Research Lab, he eventually created Chitrakar, a system that can transform an image into a drawing composed of a single, long line, ultimately turning it into a Jordan curve. In Hindi\/Sanskrit, the word Chitrakar means &#8216;painter,&#8221; or the one who creates a painting. <\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2021\/1-chitrakarasy.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2021\/1-chitrakarasy.jpg\" data-sub-html=\"Credit: Singhal et al.\">\n<figure class=\"article-img text-center\"><img decoding=\"async\" src=\"https:\/\/scx1.b-cdn.net\/csz\/news\/800\/2021\/1-chitrakarasy.jpg\" alt=\"Chitrakar: A system that can transform images of human faces into drawings\"\/><figcaption class=\"text-left text-darken text-truncate text-low-up mt-3\">\n                Credit: Singhal et al.<br \/>\n            <\/figcaption><\/figure>\n<\/div>\n<\/div>\n<p>&#8220;Our system uses state-of-the-art, deep-learning techniques to segment the human face from a photo and combined this with image enhancements techniques,&#8221; Singhal said. &#8220;The enhanced image is stippled, and the points are connected by a TSP solver where each point is assumed to be a destination of a traveling salesman. The final route of traveling salesman is converted to a Jordan curve by an intersection removal technique.&#8221;<\/p>\n<p>Chitrakar, the system created by the researchers, can autonomously convert any image of a human face into a Jordan curve. Subsequently, this Jordan curve is drawn on a piece of paper by a robotic gripper, ultimately creating artistic TSP portraits.<br \/>\n                                            <!-- Google middle Adsense block --><\/p>\n<p>&#8220;It is an engineering feat to be able to combine state-of-the-art deep-learning methods, image processing and robotics to enable a robotic arm to draw a portrait in its own unique style,&#8221; Singhal explained. &#8220;It is satisfying to see a robot drawing your face in a unique style.&#8221;<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2021\/2-chitrakarasy.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2021\/2-chitrakarasy.jpg\" data-sub-html=\"Credit: Singhal et al.\">\n<figure class=\"article-img text-center\"><img decoding=\"async\" src=\"https:\/\/scx1.b-cdn.net\/csz\/news\/800\/2021\/2-chitrakarasy.jpg\" alt=\"Chitrakar: A system that can transform images of human faces into drawings\"\/><figcaption class=\"text-left text-darken text-truncate text-low-up mt-3\">\n                Credit: Singhal et al.<br \/>\n            <\/figcaption><\/figure>\n<\/div>\n<\/div>\n<p>The robotic gripper designed by Singhal and his colleagues can hold a variety of different pens, which produce slightly different drawings (e.g., with thinner\/thicker lines, of a different color, etc.).
