Abstract: Systems and methods for managing an in-person transaction process are provided. In example embodiments, a network system receives, from a first user device, information regarding a service or an item. Using the received information, the network system generates an unpublished listing and associates the unpublished listing with a session identifier. The unpublished listing is temporarily stored to a datastore. The network system then generates a scannable code that provides a uniform resource identifier (URI) associated with the session identifier. The scannable code is presented on the first user device, whereby the scannable code can be scanned by a second user device to access, via the URI, a transaction user interface associated with the session identifier. In response to a request to access the transaction user interface triggered by the second user device scanning the scannable code, the transaction user interface is displayed on the second user device.

Abstract: An object counting system crops images into multiple split images. When a distance between at least one side of a bounding box being associated with a position of a first object in the first split image and at least one side of a bounding box being associated with a position of a second object in the second split image adjacent to the first split image is less than a tolerance value, the processor combines the adjacent first split image and the second split second split image into a merged image, so that the first object and the second object are merged into a merged object. A processor calculates a prediction number of objects based on the objects contained in these split images and the merged objects in the merged image. The object counting system automatically counts the number of bug eggs, to save manpower and provide an accurate count.
