Sign Language is at the same time a very promising and challenging field of study given the big number of hearing impaired people who cannot express their needs and communicate with others. Keywords: Sign Language (SL) Kinect camera Depth sensor Hand gesture recognition The results prove that our system can outperform previous methods using the same dataset. Our approach is also applied to a public dataset in order to be compared in the existing studies. The experimental results clearly show that the proposed system is very satisfactory as it to recognizes the French alphabet sign with an accuracy of more than 93%.
Our approach is applied on French sign language alphabet to show its effectiveness and evaluate the robustness of the proposed descriptors. These features are invariant to scale, rotation and translation. Moreover, new descriptors are introduce to model the hand gesture. Given the complexity of this task, a new method based on edge detection is proposed to eliminate the noise and segment the hand. Although this camera provides two types of information "Depth Map" and "RGB Image", only the depth data information is used to analyze and recognize the hand gestures.

Make sure the drivers are installed properly.Some microscopy software is made to interact with multiple cameras and if you don't have your specific camera selected the software will not show you a live image on the computer monitor. Make sure you have the correct camera model selected within the software.Make sure this cap is removed before using the microscope and trying to view samples with your digital camera.Įach microscope digital camera uses different software, but some of the troubleshooting tips are similar across many camera interfaces. Many stereo microscopes come with a black protective cap that is screwed onto the bottom of the body to protect the lenses. If it is slightly between positions the image will not be projected up to the camera properly. If you are using a high power compound biological microscope, make sure that your objective lens is clicked all the way into position. However, cameras require extra light in order to be able to pick up that same image, so make sure you have a brightly lit sample under the microscope.Īre objectives clicked into place and caps removes off stereo objectives? Many times when you look through a stereo microscope without the light on you might still be able to see the image. Particularly on a stereo microscope - is the light on? Many camera sensors are sensitive and if your image is not in focus the camera might not pick it up. The beam splitter will either be a switch or a lever you can pull out and push in.ĭo you have a specimen under the microscope and in focus?īefore you try to view images through the camera or on your computer screen, make sure that your sample is under the microscope, the light is turned on and it is in focus. You will find the beam splitter on the side of the head of your microscope. When the beam splitter is not pulled out or engaged, the light will not travel up to the camera and you will not be able to view an image at the camera. The microscope beam splitter directs light up the trinocular port to the camera. Is your microscope beam splitter engaged? Below you will find some troubleshooting tips for viewing live images on the camera or computer monitor from your digital microscope.
However, there is nothing more frustrating than not being able to view an image on your computer monitor from your digital microscope. Digital microscopy and microscope cameras and software are fantastic additions to the world of microscopy.
