AK-Cam's computer vision functionalities

  • Face Tracking:[step1]Prepare at least two captured frames then  one has at least one human face. [step2]Right click on a captured frame that has the human face then you will see the the frame attribute dialog and enable the "Face Track Target" check-box. [step3]Right click on an other frame then you will see the frame attribute dialog and enable the "Mask of a detected face" check-box. This frame is called "Mask Frame". [step4]Left click on a mask frame to move forward this frame. [step5]Move your face and check the result. [NOTE]The face detect target frame should be on the bottom of the rendering order.
  • Vision Mouse:The vision mouse is a mouse that uses the marker as the pointer that has the significant color(e.g. green). The AK-Cam's vision mouse will detect this marker's tilt and position then uses these informations to manipulates frames on the AK-Cam's view. [step1]Prepare at least two captured frames then at least one has the marker image in this frame. This frame is called "Vision Mouse Master". [step2]Select the vision mouse master and enable the "Vision Mouse Master" check-box on the setting dialog attached in the right of the view. Then vision mouse master frame can manipulate the vision mouse using the marker. The vision mouse master will be the bottom of the rendering order automatically. [step3]Select the "Move" edit-mode and overlap an other frame to the vision mouse master. [step4]Select the "VisionMouse" edit-mode and cut out the marker region on the vision mouse master by dragging on the vision mouse master. If the marker has the significant color on the image of this frame, the green rectangle will converges toward the marker and then you succeeded in preparing the vision mouse.  The center point of this rectangle is the "hot spot" of the vision mouse. [step5]Move the marker on a overlapped other frame and roll or pitch the marker and check the hot-spot color. If the green hot-spot appears then the vision mouse in the "click" state. Roll or pitch the marker to get the "click" state. If the white hot-spot appears then the vision mouse in the "hover" state. Set the marker to the initial orientation. If you want to drag with the vision mouse, move the marker with "click" state then hot-spot will be "red". Red hot-spot represents "drag" state. You can drag other frames with this state.
