摘要：A facility is provided for recognizing blank and nearly blank images. In variousembodiments, the facility receives an indication of an image, creates an analysis imagebased on the received image by detecting edges, determines an edge ratio for the

analysis image, determines whether the edge ratio exceeds a threshold and, when theedge ratio does not exceed the threshold, identifies the received image as a blank image.The facility can include an edge detector component that creates an analysis imagebased on a selected image by detecting edges in the selected image, a calculatorcomponent that calculates an edge ratio for the analysis image, and an analysiscomponent that determines whether the calculated edge ratio exceeds a threshold.
