The anatomical landmarks contain the characteristics that are used to guide the gastroenterologists during the endoscopy. The expert can also ensure the completion of examination with the help of the anatomical landmarks. Automatic detection of anatomical landmarks in endoscopic video frames can be helpful for guiding the physicians during screening the gastrointestinal tract (GI). Method. This study presents an automatic novel method for anatomical landmark detection of GI tract from endoscopic video frames based on semisupervised deep convolutional neural network (CNN) and compares the results with supervised CNN model. We consider the anatomical landmarks from Kvasir dataset that includes 500 images for each class of Z-line, pylorus, and cecum. The resolution of these images varies from 750\u2009\u00d7\u2009576 up to 1920\u2009\u00d7\u20091072 pixels. Result. Experimental results show that the supervised CNN has highly desirable performance with accuracy of 100%. Also, our proposed semisupervised CNN can compete with a slight difference similar to the CNN model. Our proposed semisupervised model trained using 1, 5, 10, and 20 percent of training data records as labeled training dataset has the average accuracy of 83%, 98%, 99%, and 99%, respectively. Conclusion. The main advantage of our proposed method is achieving the high accuracy with small amount of labeled data without spending time for labeling more data. The strength of our proposed method saves the required labor, cost, and time for data labeling.<\/jats:p>","DOI":"10.1155\/2022\/8151177","type":"journal-article","created":{"date-parts":[[2022,2,23]],"date-time":"2022-02-23T19:20:16Z","timestamp":1645644016000},"page":"1-14","source":"Crossref","is-referenced-by-count":4,"title":["Proposing Novel Data Analytics Method for Anatomical Landmark Identification from Endoscopic Video Frames"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5905-4017","authenticated-orcid":true,"given":"Shima","family":"Ayyoubi Nezhad","sequence":"first","affiliation":[{"name":"School of Industrial and Systems Engineering, Tarbiat Modares University (TMU), Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5824-9798","authenticated-orcid":true,"given":"Toktam","family":"Khatibi","sequence":"additional","affiliation":[{"name":"School of Industrial and Systems Engineering, Tarbiat Modares University (TMU), Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5688-2776","authenticated-orcid":true,"given":"Masoudreza","family":"Sohrabi","sequence":"additional","affiliation":[{"name":"Gastrointestinal and Liver Diseases Research Center, Iran University of Medical Sciences (IUMS), Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"year":"2020","author":"WHO","article-title":"Cancer","key":"1"},{"doi-asserted-by":"publisher","key":"2","DOI":"10.1007\/s10916-017-0836-y"},{"doi-asserted-by":"publisher","key":"3","DOI":"10.1055\/s-2001-42537"},{"doi-asserted-by":"publisher","key":"4","DOI":"10.1016\/j.compbiomed.2019.103351"},{"doi-asserted-by":"publisher","key":"5","DOI":"10.1016\/b978-0-12-802511-6.00003-x"},{"doi-asserted-by":"publisher","key":"6","DOI":"10.1016\/b978-0-323-40232-3.00004-2"},{"author":"K.
