Abstract
Various embodiments disclosed relate to a method and system for quantifying the flow speed of glass liquid from digital video data. The present disclosure includes capturing images from a video, cropping an area from each image, and concatenating the area from each image into a single image. Additionally, the disclosure includes preprocessing the single image, performing template matching on the preprocessed single image, determining boundary indexes, and cropping a region from the preprocessed single image based on the boundary indexes. The disclosure also includes calculating gradients in the cropped region, identifying a pixel with a maximum gradient, determining an average row index for columns with multiple pixels, performing iterative linear regression on row and column indexes to find a line crossing all the maximum gradient pixels with the least error, and quantifying a flow speed of glass liquid based on a final slope of the line.
