  • Publication number: 20250259279
    Abstract: Embodiments of the present disclosure provide a method for optimizing a base image library, an apparatus for optimizing a base image library, an electronic device, and a storage medium. The method includes: determining a first base image and a plurality of second base images from the base image library; calculating a difference between the first base image and each of the plurality of second base images respectively, and obtaining a plurality of residual images based on the calculation result; and deleting, in response to determining based on the plurality of residual images that shading interference is present in the first base image, the first base image from the base image library. The method for optimizing a base image library provided in the present disclosure can delete base images with shading interference from the base image library, and can improve the accuracy of fingerprint identification by the fingerprint sensor.

  • Patent number: 6728593
    Abstract: A system for analyzing fabric surface appearance includes a feed mechanism for running a fabric over a crest including a frame for holding the fabric bent to form a crest, an image capturing device for capturing profile images of the fabric surface at the crest, and a computer system for manipulating the images. The computer system produces a three-dimensional representation of the fabric surface and identifies characteristics in the three-dimensional representation. The information is compared to reference data to identify a grade for the fabric.

The computer system produces a three-dimensional representation of the fabric surface and identifies prominent characteristics in the three-dimensional representation. The information is compared to reference data to identify a grade for the fabric.
