In order to make this project, you\u2019ll need a single-color cloth. The cloth should not contain any other color visible.

If any other color is visible in our cloak then we have to process the image frame for that color also.<\/p>\n<p><strong>Note:<\/strong><\/p>\n<ul>\n<li>Cloth color should be unique relative to the background. (i.e. If the cloth is green then the background shouldn&#8217;t contain any green color)<\/li>\n<li>In good lighting conditions, it works best.<\/li>\n<li>Try to choose red, green or blue cloth, because these three colors are easier to detect.<\/li>\n<\/ul>\n<h3>Color Detection &amp; Segmentation<\/h3>\n<p>So what is Color Detection and Segmentation in Image Processing?<\/p>\n<p>Color detection is a technique where we can detect any color in a given range of HSV color space.<\/p>\n<p>Image segmentation is the process of labeling every pixel in an image, where each pixel having the same label shares certain characteristics.<\/p>\n<h3>Project Prerequisites:<\/h3>\n<ul>\n<li>Python &#8211; 3.x (we used Python 3.7.10 in this project)<\/li>\n<li>Numpy &#8211; 1.19.2<\/li>\n<li>OpenCV &#8211; 4.5<\/li>\n<\/ul>\n<p>To install opencv, run the below command.

It looks like the person has vanished.<\/p>\n<p>In this machine learning project, we have created Invisible Cloak using OpenCV. We implemented color detection and segmentation technique. In this opencv project, we learned about morphological operations, masking, and other image processing concepts.<\/p>\n<p>This project is very popular and exciting for beginners. It teaches real-time video processing, color detection, and OpenCV operations. It also shows how creative you can get with computer vision. It\u2019s perfect for making fun YouTube or Instagram videos and learning OpenCV basics.<span hidden class=\"__iawmlf-post-loop-links\" data-iawmlf-links=\"[{&quot;id&quot;:2500,&quot;href&quot;:&quot;https:\\\/\\\/drive.google.com\\\/file\\\/d\\\/15z0UcCSsxkzoTwHZKUKla2bUoqnE_kVx\\\/view?usp=drive_link&quot;,&quot;archived_href&quot;:&quot;http:\\\/\\\/web-wp.archive.org\\\/web\\\/20260601062717\\\/https:\\\/\\\/drive.google.com\\\/file\\\/d\\\/15z0UcCSsxkzoTwHZKUKla2bUoqnE_kVx\\\/view?usp=drive_link&quot;,&quot;redirect_href&quot;:&quot;&quot;,&quot;checks&quot;:[{&quot;date&quot;:&quot;2026-06-01 06:56:41&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-06-05 07:28:05&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-06-08 17:39:54&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-06-14 18:14:06&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-06-21 02:24:24&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-06-24 12:03:06&quot;,&quot;http_code&quot;:200}],&quot;broken&quot;:false,&quot;last_checked&quot;:{&quot;date&quot;:&quot;2026-06-24 12:03:06&quot;,&quot;http_code&quot;:200},&quot;process&quot;:&quot;done&quot;},{&quot;id&quot;:365,&quot;href&quot;:&quot;https:\\\/\\\/docs.opencv.org\\\/master\\\/d9\\\/d61\\\/tutorial_py_morphological_ops.html&quot;,&quot;archived_href&quot;:&quot;http:\\\/\\\/web-wp.archive.org\\\/web\\\/20211020080443\\\/https:\\\/\\\/docs.opencv.org\\\/master\\\/d9\\\/d61\\\/tutorial_py_morphological_ops.html&quot;,&quot;redirect_href&quot;:&quot;&quot;,&quot;checks&quot;:[{&quot;date&quot;:&quot;2025-12-08 09:15:18&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2025-12-12 05:12:31&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2025-12-15 09:30:53&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2025-12-20 14:37:04&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2025-12-23 15:33:48&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2025-12-30 23:38:59&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-01-10 16:59:59&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-01-17 09:16:50&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-01-20 11:58:49&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-01-23 20:11:29&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-01-27 03:55:31&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-02-02 07:01:41&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-02-16 18:15:41&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-02-23 09:44:59&quot;,&quot;http_code&quot;:403},{&quot;date&quot;:&quot;2026-02-26 15:02:37&quot;,&quot;http_code&quot;:403},{&quot;date&quot;:&quot;2026-03-04 14:24:13&quot;,&quot;http_code&quot;:403},{&quot;date&quot;:&quot;2026-03-08 14:12:43&quot;,&quot;http_code&quot;:403},{&quot;date&quot;:&quot;2026-03-12 13:36:14&quot;,&quot;http_code&quot;:403},{&quot;date&quot;:&quot;2026-03-15 16:54:56&quot;,&quot;http_code&quot;:403},{&quot;date&quot;:&quot;2026-03-23 21:26:30&quot;,&quot;http_code&quot;:403},{&quot;date&quot;:&quot;2026-03-28 05:06:29&quot;,&quot;http_code&quot;:403},{&quot;date&quot;:&quot;2026-04-03 14:21:47&quot;,&quot;http_code&quot;:403},{&quot;date&quot;:&quot;2026-04-08 05:50:25&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-04-11 16:27:46&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-04-17 01:04:28&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-04-20 15:47:58&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-04-26 00:30:40&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-05-04 03:05:50&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-05-09 09:11:30&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-05-17 15:26:47&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-05-24 15:36:14&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-06-02 13:48:00&quot;,&quot;http_code&quot;:200},{&quot;date&quot;:&quot;2026-06-05 16:47:21&quot;,&quot;http_code&quot;:404},{&quot;date&quot;:&quot;2026-06-09 01:45:55&quot;,&quot;http_code&quot;:404},{&quot;date&quot;:&quot;2026-06-14 18:15:19&quot;,&quot;http_code&quot;:404},{&quot;date&quot;:&quot;2026-06-21 02:24:24&quot;,&quot;http_code&quot;:404},{&quot;date&quot;:&quot;2026-06-24 12:03:23&quot;,&quot;http_code&quot;:404}],&quot;broken&quot;:true,&quot;last_checked&quot;:{&quot;date&quot;:&quot;2026-06-24 12:03:23&quot;,&quot;http_code&quot;:404},&quot;process&quot;:&quot;done&quot;}]\"><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Are you fascinated with Harry Potter&#8217;s Invisible Cloak?
