Abstract

A person detection apparatus and method, and a privacy protection system using the method and apparatus, the person detection apparatus includes: a motion region detection unit, which detects a motion region from a current frame image using motion information between frames; and a person detecting/tracking unit, which detects a person in the detected motion region using shape information of persons, and performs a tracking process on a motion region detected as the person in a previous frame image within a predetermined tracking region.

Claims

1. An image processing method comprising:

receiving an image;

detecting a face in the image; and

performing a process on the detected face in the image to protect personal privacy using a person detecting apparatus.

2. The method of claim 1, wherein the image is a frame image.

3. The method of claim 1, wherein the image is one of video images.

4. The method of claim 1, wherein the process includes mosaic process.

5. An image processing method comprising:

receiving a street image;

detecting a face in the street image; and

performing a process on the detected face in the street image to protect personal privacy using a person detecting apparatus.

6. The method of claim 5, wherein the process includes mosaic process.

7. An image processing method comprising:

receiving a street image, the street image comprising at least one street, at least one face, and at least one building;

detecting a face in the street image, the face in the street image being located in front of the building; and

performing a process on the detected face in the front of the building in the street image to protect personal privacy using a person detecting apparatus.

8. The method of claim 7, wherein the process includes mosaic process.
