determination and procedure of the hand position

To determine the hand, in the moving image search for the hand and determines their position in screen coordinates. Whose position is described by an image mask.
A pixel is marked if it assigned position of the hand can be. In addition, the location of the center point calculated by hand.

I would first like to narrow down the area of the image, the closest hand.
it is given a random search. The color values randomly selected pixels with the color values of the hand are compared.
What is the color values of the hand is determined in a histogram. As a guest
area now the area is delimited, in which the density of the pixels is highest.
in this area was limited, it is also the hand.
The area is defined by a starting point (xS, yS) and
an endpoint (xE, yE). Start and end point in image coordinates described.

be seen in the image were identified a few pixels of the hand. Through a Segmentation in the restricted space BS the entire palm is exposed. For this, a region growing algorithm is used. As a starting point for the algorithm
the center of the area BS is chosen. From this starting point
the color values \u200b\u200bof all neighbors are compared with the color values \u200b\u200bthat are defined as the color of hand
. It defines no fixed color value but a range of colors.
If a color value in the desired range of colors, the pixel marked in an image mask.
Each field in the mask corresponds to one pixel in the video image. Then
the other neighbors are examined. The process stops when none can be found further
more pixels that correspond to the values \u200b\u200bdefined area of \u200b\u200bthe hand
or if the edge of the area BS is achieved. The result of region growing-
algorithm is the segmented surface of the hand.

side of the area is the edge pixel is determined and marked in the image mask.
by the contour of the hand is determined.

Next, check whether the segmented area and the contour of the hand is
. But two features are defined, being tested set of rules: first

The number of segmented pixels in relation to the surface of the fenced area BS.

second The number of edge pixels in proportion to the area BS.

Are the characteristics of the segmented areas the desired characteristics such
defines the area as a hand. Otherwise, the process is interrupted and continued until the next
recorded video image.

Rahmenbedingung

Für die Realisierung des Spiels PONG, die nur mit Hilfe der Hand über die WebCam gesteuert werden soll, möchte ich erst einmal, die Rahmenbedingungen festlegen.
Mit dem Einsatz von Algorithmen und Techniken der Bildverarbeitung und mit Hilfe der Webcam, die Hand als Hand zuerkennen und anschließend durch die „erkannte“ Hand und Bestimmung der Position der Hand, den Balken des Spiels PONG, in Echtzeit über die Hand zusteuern.
Im ersten Schritt, möchte ich die Rahmenbedingung in einfachster Form festlegen und nach erfolgreicher Realisierung diese erweitern.
Für eine gelungene Bildaufnahme bzw. zum Erkennung der Hand möchte I place the following conditions.

• need the hand of the player are of the reception area.
• The palm should be moved in the direction of the camera.
• For a start I would like to select a monotonous background which the hand is easier to determine.

the beginning of the implementation phase, I will decide for example, a monotonous background color that is not identical with the skin color. This could for example be the color blue or green.
After a successful test results, I would then expand this to all sorts of backgrounds.

is interesting in it Wonder how I will recognize the hand of a hand. There are several image processing algorithms. One way to use that I want is the recognition of the hand by determining color values.
problems that can arise with this method is, for example, that the hand of the player, directly in front of the player would face. In such a situation, one would have the hand may be different from the face.

Project Start: PONG game - steering the beams by hand to the Webcam

In the study - image recognition - we got the great task of building the PONG game so far that the bar in the game PONG exclusively by hand can be controlled from the webcam. As a technical tool us is only a WebCam (standard) are available. The use of webcams is intended to ensure that the hand is detected as a single source. The moving image has to be continually evaluated. Important here is the question of where is currently a hand in the moving image? How do I distinguish the hand from the face or other objects that may be in the frame of the moving image. By moving the hand (up, down, left to right) bar should be moved in the game. With this approach, it should be possible to control the game with the hand, is used without a mouse, joystick or keyboard.

this task deal with, I will first investigate once to find out which techniques such as algorithms, formulas, methods are used for example in image recognition. These new insights will certainly help me in my solutions. I am still at the beginning of my research and I have no knowledge of the techniques used in image recognition. An important aspect is also the one that we must recognize here the hand in moving images and the detected image, translate, so the bar that we can control the game PONG in real time.
