The data was trained using Google&#8217;s online classifier[1]. A TensorFlow model was then exported and further used for detecting where exactly in the image or video frames a disaster is found.  <\/p>\n\n\n\n<p class=\"tw-text-wide has-large-font-size\" style=\"line-height:1.5\">In order to convert the classifier to an object detector, upon capturing video frames, the image is rescaled to smaller images like a pyramid. Then, for each rescaled&nbsp; frame a sliding window with a fixed size is passed through the image and classifying each region of interest.&nbsp; These classifications are converted to boxes, therefore having multiple sized boxes depending on frame size. Finally, non-maxima suppression is used on these boxes to get the final detection boxes on the original frame.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image alignwide size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"942\" height=\"487\" src=\"https:\/\/www.kios.ucy.ac.cy\/ARTION\/wp-content\/uploads\/2022\/02\/diagramsDisasterDetector.jpg\" alt=\"\" class=\"wp-image-398\" srcset=\"https:\/\/www.kios.ucy.ac.cy\/ARTION\/wp-content\/uploads\/2022\/02\/diagramsDisasterDetector.jpg 942w, https:\/\/www.kios.ucy.ac.cy\/ARTION\/wp-content\/uploads\/2022\/02\/diagramsDisasterDetector-300x155.jpg 300w, https:\/\/www.kios.ucy.ac.cy\/ARTION\/wp-content\/uploads\/2022\/02\/diagramsDisasterDetector-768x397.jpg 768w\" sizes=\"auto, (max-width: 942px) 100vw, 942px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1006\" src=\"https:\/\/www.kios.ucy.ac.cy\/ARTION\/wp-content\/uploads\/2022\/02\/disasterDetector-1024x1006.jpg\" alt=\"\" class=\"wp-image-399\" srcset=\"https:\/\/www.kios.ucy.ac.cy\/ARTION\/wp-content\/uploads\/2022\/02\/disasterDetector-1024x1006.jpg 1024w, https:\/\/www.kios.ucy.ac.cy\/ARTION\/wp-content\/uploads\/2022\/02\/disasterDetector-300x295.jpg 300w, https:\/\/www.kios.ucy.ac.cy\/ARTION\/wp-content\/uploads\/2022\/02\/disasterDetector-768x755.jpg 768w, https:\/\/www.kios.ucy.ac.cy\/ARTION\/wp-content\/uploads\/2022\/02\/disasterDetector.jpg 1026w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<p class=\"tw-text-wide\"><a href=\"#_ftnref1\">[1]<\/a> Teachable Machine<em>.<\/em>&nbsp;(last accessed on 1\/2\/2022) <a rel=\"noreferrer noopener\" href=\"https:\/\/teachablemachine.withgoogle.com\/\" target=\"_blank\">https:\/\/teachablemachine.withgoogle.com\/<\/a><\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group alignfull\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-columns alignwide tw-gutter-large tw-cols-stack-md is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h3 class=\"wp-block-heading\" id=\"software\">Software<\/h3>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p>Code written in Python is available here: <\/p>\n\n\n\n<p><a href=\"https:\/\/zenodo.org\/record\/5938343#.YfkSQ2hBzIU\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/zenodo.org\/record\/5938343#.YfkSQ2hBzIU<\/a><\/p>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Developed by: Raphael Makrigiorgis and Elia Nicolaou Disaster detector and classifier for detecting fires, floods, and building disasters.
