METHOD AND APPARATUS FOR SEMI-AUTOMATIC FINGER EXTRACTION
First Claim
1. An image processing device comprising:
- an inputting unit for performing a click on an object image contained in an image to obtain a clicked point;
a calculating unit for calculating an edge map of the image;
an estimating unit for estimating a color model of the object image based on the clicked point and the edge map;
an object classifying unit for classifying each pixel in the image, based on the edge map and the color model, so as to obtain a binary image of the image; and
a detecting unit for detecting a region containing the object image based on the binary image.

Abstract
An image processing device includes: an inputting unit for performing a click on an object image contained in an image to obtain a clicked point; a calculating unit for calculating an edge map of the image; an estimating unit for estimating a color model of the object image based on the clicked point and the edge map; an object classifying unit for classifying each pixel in the image, based on the edge map and the color model, so as to obtain a binary image of the image; and a detecting unit for detecting a region containing the object image based on the binary image. The image processing device and method according to the present disclosure can improve the accuracy of detecting the boundary of an object image such as a finger image, thus facilitating removal of the object image from the image and making the processed image more nice-looking.
