Abstract

An instant face recognition system includes at least an image capturing module for capturing images, a picture-taking direction control module coupling with the image capturing module for controlling picture-taking direction of the image capturing module to capture user'"'"'s head images, a facial image processing module coupling with the image capturing module to detect user'"'"'s facial features from user'"'"'s head images captured by the image capturing module and compare the facial features to process recognition.

Claims

1. A face recognition system for processing face recognition through an user'"'"'s face, comprising at least:

an image capturing module for capturing images;

a picture-taking direction control module coupling with the image capturing module to control picture-taking direction of the image capturing module to capture user'"'"'s head images;

a storage module for storing a plurality of facial images for reference and comparing use, the stored facial images having been transferred to mathematical Invariant spaces in advance and being stored in the storage module in formats of Invariant faces;

a face detection module coupling with the image capturing module for detecting locations of facial images from the head images;

a facial features detection module coupling with the face detection module for detecting a plurality of facial features from the facial images, and transferring every facial feature to Invariant spaces to become an Invariant vector; and

a face recognition module for calculating Invariant vectors of the facial features and similarity degree of the Invariant faces stored in the storage module, and based on the similarity providing a confidence index.

2. The face recognition system of claim 1, wherein the image capturing module includes a video camera and a video driver to obtain RGB (Red, Green, Blue) original data of the head images.

3. The face recognition system of claim 1, wherein the picture-taking direction control module includes:

a motor coupling with the image capturing module to drive the picture-taking direction of the image capturing module; and

a picture-taking direction adjustment module coupling with the motor for adjusting turning angle of the motor.

4. The face recognition system of claim 1, wherein the storage module includes an Invariant face database and an Invariant facial features database.

5. The face recognition system of claim 1, wherein the calculating Invariant vectors of the facial features and similarity degree of the Invariant faces stored in the storage module are accomplished by employing Invariant Hadamard Transform algorithm or Invariant Critical Element Analysis.

6. The face recognition system of claim 1, wherein the face detection module is driven by an input module.

7. The face recognition system of claim 6, wherein the input module couples with the face recognition system and is selected from the group consisting of mouse devices, electric door locks, card readers or keyboards.

8. A face recognition system for processing face recognition through an user'"'"'s face, comprising at least:

an image capturing module for capturing images;

a picture-taking direction control module coupling with the image capturing module to control picture-taking direction of the image capturing module to capture user'"'"'s head images; and

a facial image processing module coupling with the image capturing module for detecting user'"'"'s facial features from the user'"'"'s head images captured by the image capturing module and processing recognition for the facial features;

9. The face recognition system of claim 8, wherein the image capturing module includes a video camera and a video driver to obtain RGB (Red, Green, Blue) original data of the head images.

10. The face recognition system of claim 8, wherein the picture-taking direction control module includes:

a motor coupling with the image capturing module to drive the picture-taking direction of the image capturing module; and

a picture-taking direction adjustment module coupling with the motor for adjusting turning angle of the motor.

11. The face recognition system of claim 8, wherein the facial image processing module includes at least:

a storage module for storing a plurality of facial images for reference and comparing use, the stored facial images having been transferred to mathematical Invariant spaces in advance and being stored in the storage module in formats of Invariant faces;

a face detection module coupling with the image capturing module for detecting locations of facial images from the head images;

a facial features detection module coupling with the face detection module for detecting a plurality of facial features from the facial images, and transferring every facial feature to Invariant spaces to become an Invariant vector; and

a face recognition module for calculating Invariant vectors of the facial features and similarity degree of the Invariant faces stored in the storage module, and based on the similarity providing a confidence index.

12. The face recognition system of claim 11, wherein the storage module includes an Invariant face database and an Invariant facial features database.

13. The face recognition system of claim 11, wherein the calculating Invariant vectors of the facial features and similarity degree of the Invariant faces stored in the storage module are accomplished by employing Invariant Hadamard Transform algorithm or Invariant Critical Element Analysis.

14. The face recognition system of claim 11, wherein the face detection module is driven by an input module.

15. The face recognition system of claim 14, wherein the input module couples with the face recognition system and is selected from the group consisting of mouse devices, electric door locks, card readers, sensors or keyboards.
