Abstract

An image masking method is provided. The method includes: extracting an object from an image; obtaining characteristic information about the extracted object by analyzing the extracted object; determining whether the extracted object is a masking target according to an input setting value or the obtained characteristic information; and performing masking such that the obtained characteristic information is reflected on the extracted object, in response to determining that the extracted object is the masking target among a plurality of objects extracted from the input image, wherein the setting value is set by an input designating at least a partial region in the input image, and wherein in the determining whether the extracted object is the masking target, an object positioned in the at least a partial region is determined as the masking target among the extracted objects.

First claim

What is claimed is:

1. An image masking method of a surveillance system in which a processor and a memory are included and an operation is controlled by the processor, the image masking method comprising:
extracting an object from an image;
obtaining characteristic information of the extracted object by analyzing the extracted object in an image;
designating a specific region in the image based on a user input;
comparing the characteristic information with a database to analyze whether the extracted object is a registered person;
selecting the extracted object as a masking target when the extracted object is not the registered person;
detecting whether the extracted object is positioned in the specific region; and
performing selective masking on the extracted object according to whether the extracted object is positioned in the specific region,
wherein the performing of the selective masking includes:
not performing masking on the extracted object that is positioned outside of the specific region, and
performing the masking on the extracted object when the extracted object enters the specific region.

2. The image masking method of claim 1 , wherein the obtained characteristic information is a characteristic information for monitoring the extracted object.

3. The image masking method of claim 2 , wherein in the performing masking on the extracted object, the obtained characteristic information is reflected on the extracted object.

4. The image masking method of claim 3 , wherein a silhouette is displayed in the image according to shape information about the extracted object.

5. The image masking method of claim 1 , the characteristic information of the extracted object is displayed together with and adjacent to the image.

6. The image masking method of claim 3 , wherein the obtained characteristic information comprises information about at least one of color, shape, motion, identity and position.

7. The image masking method of claim 1 , wherein the performing the masking comprises:
generating a masking object by reflecting the obtained characteristic information; and
performing the masking on the extracted object determined as a masking target using the masking object.

8. The image masking method of claim 7 , wherein the masking object is an avatar on which the obtained characteristic information is reflected.

9. The image masking method of claim 8 , wherein at least one of a face, a hair, a top, a bottom, a gender, and an age of the avatar is determined according to the obtained characteristic information.
