During his talk, which took place at the \u003Ca href=\u0022http:\/\/www.vap.aau.dk\/cvsports\/\u0022\u003E4th International Workshop on Computer Vision in Sports (CVsports)\u003C\/a\u003E\u0026nbsp;in June, he also discussed the challenges that computer vision scientists face when creating technology to improve the sports industry.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EOne such challenge is computer vision and machine learning being used to create models that can identify common sports scenes and help write news captions. But what humans easily interpret is often not so simple for machines.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EWhen analyzing a photo of Georgia Tech\u0026rsquo;s head football coach Paul Johnson getting a celebratory Gatorade bath on the field, a computer algorithm misidentified a\u0026nbsp;camera in the scene as a hair dryer, and the resulting caption read \u0026ldquo;Man taking shower while others watch.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EImproving computer vision so that it is able to better account for things like context and have better training models is one of the next steps in the field.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EScientists are also working on how to make this type of technology available for use on lower-quality video. Current computer vision techniques work well for broadcast-quality video in part because of the detail available in high-definition, but researchers would like to make the techniques accurate and cost-effective for lower-quality video so that high school sports can also take advantage of their benefits.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EBy 2019, video content is expected to account for 80 percent of the world\u0026rsquo;s total web content. Computer vision\u0026rsquo;s ability to understand context, analyze lower-quality video content, and establish better metrics to analyze the data are all key next steps for this segment of computer science, according to Essa.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe workshop took place as part of the CVF\/IEEE \u003Cstrong\u003E\u003Ca href=\u0022http:\/\/cvpr2018.thecvf.com\/\u0022\u003EComputer Vision and Pattern Recognition (CVPR)\u003C\/a\u003E\u003C\/strong\u003E conference in Salt Lake City, Utah.
