Abstract: A computer-implemented method includes capturing, with a camera, a first image of a physical item at a first camera position, detecting borders associated with the physical item, based on the first image, generating an overlay that includes a plurality of objects that are positioned within one or more of the borders associated with the physical item, capturing, with the camera, subsequent images of the physical item, where each subsequent image is captured with a respective subsequent camera position, and during capture of the subsequent images, displaying an image preview that includes the overlay. The method further includes establishing correspondence between pixels of the first image and pixels of each of the subsequent images and generating a composite image of the physical item, where each pixel value of the composite image is based on corresponding pixel values of the first image and the subsequent images.
