This is due to the un-defined edge and the complex flow nature of turbulence. In this paper, an image-based technique is proposed for turbulent flow segmentation from image. The proposed technique segments the flow region based on enhancing the input image intensity at flow edges and by defining a thresholding value to differentiate between flow region and image background. To test the image-based segmentation technique, a turbulent buoyant jet was experimentally simulated at different nozzle flow rates which have a Reynolds numbers of 960, 1560, and 3210. Then, a video camera was used to record the jet flow data. Then, the image-based technique was applied to segment the flow region and estimate the jet penetration area. As a result, the turbulent flow region was segmented well for all cases of nozzle flow rates. Moreover, application of the image-based technique for jet penetration estimation showed a good agreement with the previous work, in which the jet propagated linearly over time. © 2018, Springer Nature Singapore Pte Ltd. date: 2018 publisher: Springer Verlag official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85043319435&doi=10.1007%2f978-981-10-8276-4_12&partnerID=40&md5=72941a8f56a6e247b3d19d0aa8d27917 id_number: 10.1007/978-981-10-8276-4₁₂ full_text_status: none publication: Lecture Notes in Electrical Engineering volume: 488 pagerange: 119-129 refereed: TRUE isbn: 9789811082757 issn: 18761100 citation: Osman, A.B. and Ovinis, M. and Faye, I. and Hashim, F.M.
