Vision-based processing of unrecognized self-checkout items

Abstract

Abstract Methods and systems for a vision-based processing of unrecognized items in self-checkout (SCO) environments that create visual exclusion zones for previously identified items. Top-down camera views are used to generate bounding boxes around items, comparing aspect ratios and center points to determine if items have moved. After an unrecognized item is identified through scanning or selection, a dead zone is created in that region, preventing repeated prompting for the same item while allowing new items to be detected. The dead zone is automatically cleared when the area is empty or when a new item with different characteristics appears in that location, improving transaction speed, accuracy, and customer experience while reducing the need for attendant intervention.
