Abstract

The present invention relates to an image-adjusting system and method, and more particularly, to a system and method for adjusting a facial image. By a set of adjusting parameters that by using a face-adjusting template stored in a database of face-adjusting template to adjust the image data of a facial image, wherein the database of face-adjusting template comprises plural data of face adjustment parameter generated by computer software or manual adjustment, such as skin texture, proportion of facial features, and variations of expression, etc., for improving the quality of a facial image, moreover, the arrangement and combination of the plural face adjustment parameters can further constitute different face-adjusting templates, so that the facial expression may be appropriately modified to generate the effect of different facial images.

Claims

1. An image-adjusting system for facial image, comprising:

an image-reading unit, for reading an original facial image;

a feature detection unit, for recognizing and positioning facial characteristics of the facial image;

a face-adjusting template database, for storing a plurality of face-adjusting templates that are preset, wherein each different face-adjusting template further comprises different face adjustment parameters that are preset;

a template selection unit, for selecting a face-adjusting template having facial characteristic of intended adjustment from the face-adjusting template database, and the selected face-adjusting template is applied to the original facial image so as to modify the facial characteristic of the original facial image; and

a manual adjusting unit, which is used for adjusting the facial characteristic of the facial image manually, and may record a parameterized processing procedure and used as a new template, moreover, the new template is stored in the face-adjusting template database.

2. The image-adjusting system for facial image according to claim 1, wherein the facial characteristics of the facial i mage comprises the characteristic of the relative position and proportion of facial features of the facial image.

3. The image-adjusting system for facial image according to claim 1, wherein the facial characteristics of the facial image comprises the characteristic of the skin texture.

4. The image-adjusting system for facial image according to claim 1, wherein the preset face adjustment parameter can be a facial expression parameter of the facial image.

5. The image-adjusting system for facial image according to claim 1, wherein the preset face adjustment parameter can be a proportion parameter of facial feature of the facial image.

6. The image-adjusting system for facial image according to claim 1, wherein the preset face adjustment parameter can be a skin texture parameter.

7. The image-adjusting system for facial image according to claim 1, wherein the preset face adjustment parameter can be a skin parameter of brightness-and-contrast.

8. The image-adjusting system for facial image according to claim 1, wherein the preset face adjustment parameter can be a tint parameter of skin color.

9. The image-adjusting system for facial image according to claim 1, wherein the preset face-adjusting template can be a template having an assortment of dynamic series of facial expression variations.

10. The image-adjusting system for facial image according to claim 1, wherein the preset portrait image adjusting parameter can be a template of animated comic effect.

11. An image-adjusting method for facial image, comprising at least the following steps:

(a)loading a facial image;

(b)recognizing and positioning facial characteristics of the facial image using a feature detection unit;

(c)selecting a face-adjusting template from a face-adjusting template database;

(d)applying the adjustment parameter values of the selected face-adjusting template to the facial image for modifying the facial characteristics of the facial image;

(e)while processing step (c), making an evaluation to determine whether a proper face-adjusting template exists in the face-adjusting template database for selection, if no appropriate face-adjusting template exists, the facial image will be adjusted manually in step (c), moreover, a parameterized processing procedure is recorded and used as a new template, and the new template is stored into the face-template database;

(f)after processing step (d), adjusting the facial characteristics of the facial image manually can further be applied onto the modified facial image; and

(g)outputting the facial image that has been adjusted.

12. The image-adjusting method for facial image according to claim 11, wherein the preset face-adjusting template can be an assortment of facial expression parameters of the facial image.

13. The image-adjusting method for facial image according to claim 11, wherein the preset face-adjusting template can be an assortment of proportion parameters of facial feature of the facial image.
