By setting a one-dimensional line tool across the image and calculating the grayscale difference across this line, a series of points will be generated throughout the frames. 通過(guò)設置橫寬圖像一維線(xiàn)工具并計算橫跨線(xiàn)的灰階差異，可以在所有的幀中生成一系列的點(diǎn)。
This is an online tool which allows you to analyze frontpage stories and determine a host of factors related to the tipping point when a story goes popular. 這是一個(gè)在線(xiàn)工具，它可以讓你分析首頁(yè)文章并且找出一篇文章流行時(shí)影響它流行的關(guān)鍵點(diǎn)。
