1. An apparatus for detecting an upper body, comprising:
- an omega field detecting unit configured to detect an omega field including a shape formed of a face and a shoulder line of a human from a target image, the omega field detecting unit including;
a resizing unit configured to reduce a width or a length of the target image by a predetermined percentage;
a first feature deducing unit configured to deduce a weight of coordinates of the reduced target image and deduce a first feature on the basis of the deduced weight; and
an omega field judging unit configured to judge whether the omega field is included in the target image by comparing the first feature with a reference value;
a face detecting unit configured to detect whether the human face is included in the omega field;
a side/rear verifying unit configured to verify whether a side or a rear of a human exists in the omega field if the human face is not detected by the face detecting unit; and
an upper body judging unit configured to judge whether the upper body of a human is included in the target image on the basis of a result of detecting the human face and configured to judge whether the upper body of a human is included in the target image on the basis of a result of verifying whether a side or a rear of a human exists in the omega field.

Abstract
Disclosed is a method of detecting an upper body. The method includes detecting an omega candidate area including a shape formed of a face and a shoulder line of a human from a target image, cutting the target image into the upper body candidate area including the omega candidate area, detecting a human face from the upper body candidate area, and judging whether the upper body of the human is included in the target image according to the result of detecting the human face.

6. A method for detecting an upper body, comprising:
-
detecting an omega candidate area including a shape formed of a face and a shoulder line of a human from a target image; cutting the target image into the upper body candidate area including the omega candidate area; detecting whether a human face appears in the upper body candidate area; detecting whether a side or a rear of a human appears in the upper body candidate area if the human face is not detected in the upper body candidate area, and judging whether the upper body of the human is included in the target image according to a result of detecting the human face and according to a result of detecting wherein the omega candidate area is detected by; reducing a width or a length of the target image by a predetermined percentage, deducing a weight of coordinates of the reduced target image and deducing a first feature on the basis of the deduced weight, and judging whether the omega field is included in the target image by comparing the first feature with a reference value. - View Dependent Claims (7, 8, 9)
