Embodiment Construction

[0030] 1. Motion detection

[0031] Motion detection consists of three steps:

[0032] 1. Reference background construction

[0033] Before motion detection, it is necessary to construct a reference background based on the images captured by the camera unit. Here are two background construction methods for different situations:

[0034] Method 1: multi-frame image statistics method. This method is suitable for slow hand movement. The specific implementation method is to take multiple frames of continuous grayscale images, and use the average value of each point in the image over time as the value of the reference background at that point.

[0035] Method 2: Inter-frame reference method. This method is suitable for the case of fast hand movement, and the specific implementation method is to use the last captured image as the reference background of the currently captured image.

[0036] 2. Motion Region Extraction

[0037] After the reference background is constructed succ...

Abstract

The invention provides a method for processing a signal by dynamic gesture identification for television control, which relates to a signal processing method which detects motion in an image photographed by a television embedded camera, identifies actions of a hand and converts the action to a television control signal (such as channel switching, volume regulation, more complex menu operation and the like). The method comprises the following steps: acquiring a television user action image by the television built-in camera, analyzing the acquired image to acquire a motion region; extracting information of a hand target from the motion region to generate a track; and determining a command corresponding to the track to generate the television control command. The invention provides a method for controlling the television by a dynamic gesture through positioning the hand without manual assistance, which is to acquire a gesture language through a mode of detecting the motion and constructing a multiple objective body-models, and generate the corresponding television control command. The method provides a more improved mode of remote control for the field of gesture language television. The mode of remote control can significantly promote the development of the television application field.

Description

technical field [0001] The invention relates to motion detection from images captured by a built-in camera of a TV, recognition of human hand movements and conversion into a signal for TV control signals (such as channel switching, volume adjustment, and more complex menu operations, etc.) Approach. It belongs to the technical field of television control devices. Background technique [0002] The current modes of remote control of the TV mainly include: [0003] 1. Infrared TV Remote Controller (Infrared TV Remote Controller) remote control, [0004] 2. Remote control input similar to mouse, [0005] 3. Use the remote control handwriting input of the tablet, [0006] Although there is already a patent on remote control of TV with sign language actions, such as Chinese patent 02101991.6, this patent is based on the recognition of infrared information of human fingertips, and is not an ideal technical solution in terms of feasibility, cost and accuracy. Other similar pate...
