Abstract
A processor-implemented method with blur estimation includes: acquiring size information of an input image; resizing the input image to generate a target image of a preset size; estimating a blur of the target image; and estimating a blur of the input image based on the size information of the input image.
Claims28
A processor-implemented method with blur estimation, comprising:
- acquiring size information of an input image;
- detecting a region of interest (ROI) in the input image;
- resizing the ROI to generate a target image of a preset size;
- estimating a blur of the target image;
- and
- estimating a blur of the input image based on the estimated blur of the target image and the size information of the input image.
3 more elements
An apparatus with blur estimation, comprising:
- a memory storing computer-readable instructions;
- and
- one or more processors,
- wherein, in response to the instructions being executed by the one or more processors, the one or more processors are configured to:
- acquire size information of an input image;
- detect a region of interest (ROI) in the input image;
- resize the ROI to generate a target image of a preset size;
- estimate a blur of the target image;
- and
- estimate a blur of the input image based on the estimated blur of the target image and the size information of the input image.
7 more elements
An apparatus with user verification, comprising:
- a camera configured to capture an input image;
- and
- one or more processors configured to:
- detect a region of interest (ROI) in the input image;
- resize the ROI to generate a target image of a preset size different from a size of the input image;
- estimate a blur of the target image;
- estimate a blur of the input image based on the size of the input image, the preset size, and the estimated blur of the target image;
- perform a liveness test on the input image based on the estimated blur of the input image;
- and
- perform the user verification based on a result of the liveness test.
