The subject disclosure relates to techniques for inserting of bounding boxes around image objects. A process of the disclosed technology can include steps for receiving, from a first data set, an image comprising a first image object, processing the image to identify a pixel region associated with the first image object, and placing a first bounding box around the first image object based on the identified pixel region. In some aspects, the process further includes steps for receiving a user input comprising an indication of whether the first bounding box is accurately placed around the first image object. Systems and machine-readable media are also provided.
