The most interesting outcome of the results is that the change in clear ice extent is inversely proportional to the area of the glaciers means that the smaller glacier has much more variations as compared to the bigger glaciers. Machine learning has a significant role for automatic extraction of clear-ice when exploited with the OLI.<\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":18923,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[],"class_list":["post-406","post","type-post","status-publish","format-standard","hentry","category-research"],"_links":{"self":[{"href":"https:\/\/people.utm.my\/nadzri\/wp-json\/wp\/v2\/posts\/406","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/people.utm.my\/nadzri\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/people.utm.my\/nadzri\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/people.utm.my\/nadzri\/wp-json\/wp\/v2\/users\/18923"}],"replies":[{"embeddable":true,"href":"https:\/\/people.utm.my\/nadzri\/wp-json\/wp\/v2\/comments?post=406"}],"version-history":[{"count":6,"href":"https:\/\/people.utm.my\/nadzri\/wp-json\/wp\/v2\/posts\/406\/revisions"}],"predecessor-version":[{"id":432,"href":"https:\/\/people.utm.my\/nadzri\/wp-json\/wp\/v2\/posts\/406\/revisions\/432"}],"wp:attachment":[{"href":"https:\/\/people.utm.my\/nadzri\/wp-json\/wp\/v2\/media?parent=406"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/people.utm.my\/nadzri\/wp-json\/wp\/v2\/categories?post=406"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/people.utm.my\/nadzri\/wp-json\/wp\/v2\/tags?post=406"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
