TARGET ANALYSIS APPARATUS, METHOD AND COMPUTER-READABLE MEDIUM
First Claim
1. A target analysis apparatus having a depth image and an intensity image of a target as an input, the target analysis apparatus comprising:
- a body detection unit to detect a body of the target from the intensity image of the target;
a foreground segmentation unit to calculate an intensity threshold value in accordance with intensity values from the detected body, to transform the intensity image into a binary image using the intensity threshold value, and to mask the depth image of the target using the binary image as a mask to thereby obtain a masked depth image; and
an active portion detection unit to detect an active portion of the body of the target from the masked depth image.

Abstract
Provided is a target analysis apparatus, method and computer-readable medium based on a depth image and an intensity image of a target is provided. The target analysis apparatus may include a body detection unit to detect a body of the target from the intensity image of the target, a foreground segmentation unit to calculate an intensity threshold value in accordance with intensity values from the detected body, to transform the intensity image into a binary image using the intensity threshold value, and to mask the depth image of the target using the binary image as a mask to thereby obtain a masked depth image, and an active portion detection unit to detect an active portion of the body of the target from the masked depth image.
