Abstract

Disclosed are an apparatus and a method of detecting a human component from an input image. The apparatus includes a training database (DB) to store positive and negative samples of a human component, an image processor to calculate a difference image for the input image, a sub-window processor to extract a feature population from a difference image that is calculated by the image processor for the positive and negative samples of a predetermined human component stored in the training DB, and a human classifier to detect a human component corresponding to a human component model using the human component model that is learned from the feature population.

Claims

1. An image forming system comprising:

a photographing apparatus to photograph an image of an object;

a detecting apparatus to detect a region of the object corresponding to an object model from a difference image of the object using the object model, wherein the object model is learned from a feature population extracted from a difference image of positive and negative samples of the object;

a status parameter computing apparatus to compute status parameters based on the detected object region where the object exists in the image of the object, so as to enable the object to be in the central region of the image;

a controller to receive the status parameters and adjust the status of the image;

a storing apparatus to store the image of the object; and

a display apparatus to display the image of the object.

2. The system of claim 1 further comprising:

a marking apparatus to provide the detecting apparatus with a region of the object which is manually marked on the image by a user.

3. The system of claim 1, wherein the controller controls at least one of operations of rotation, tilting, zooming, and selecting a focus region according to the status parameters.

4. The system of claim 1, wherein the controller selects a new region where the object exists as a focus region.

5. The system of claim 1, wherein the controller makes the central region of the image as a default focus region, dynamically selects a new region where the object exists as a focus region, and controls status parameters of zoom, focal distance, rotation, or tilt based on image information of the focus region.
