Abstract
An eye reconstruction-based eye tracking method and apparatus are provided. The eye tracking method includes generating a reconstructed image by performing eye reconstruction with respect to an input image, determining a difference value between the input image and the reconstructed image, selecting one of the input image, the reconstructed image, and a replacement image as a target image based on the determined difference value, and performing eye tracking based on the target image.
Claims20
An eye tracking method comprising:
- generating a reconstructed image by performing eye reconstruction with respect to an input image;
- determining a difference value between the input image and the reconstructed image;
- selecting one of the input image, the reconstructed image, and a replacement image as a target image based on the determined difference value;
- and
- performing eye tracking based on the target image.

An electronic device comprising:
- a camera configured to obtain an input image of a user;
- a memory configured to store instructions;
- and
- a processor configured to execute the instructions to:
- generate a reconstructed image by performing eye reconstruction with respect to the input image;
- select, as a replacement image, a sample image among sample images stored in a database that has a highest similarity to the input image;
