    <p>i want to track only one person through the kinect and i wanna track its skeletal data and at the same time i want to show the depth from containing only that player but not the other players.</p> <p>Attached here is the code responsible for that, CAN anyone HELP ?!!</p> <pre><code>void mySensor_AllFramesReady(object sender, AllFramesReadyEventArgs e) { if (closing) return; using (DepthImageFrame depthFrame = e.OpenDepthImageFrame()) { if (depthFrame == null) { return; } byte[] pixels = GenerateDepthImage(depthFrame); int stride = depthFrame.Width * 4; depthImage.Source = BitmapSource.Create(depthFrame.Width, depthFrame.Height, 96, 96, PixelFormats.Bgra32, null, pixels, stride); } //Get a skeleton Skeleton first = GetFirstSkeleton(e); ProcessSkeletalData(first, e); } </code></pre> <p>and here is the method of generating depth image:</p> <pre><code>private byte[] GenerateDepthImage(DepthImageFrame depthFrame) { //get the raw data from kinect with the depth for every pixel short[] rawDepthData = new short[depthFrame.PixelDataLength]; depthFrame.CopyPixelDataTo(rawDepthData); //use depthFrame to create the image to display on-screen //depthFrame contains color information for all pixels in image //Height x Width x 4 (Red, Green, Blue, empty byte) Byte[] pixels = new byte[depthFrame.Height * depthFrame.Width * 4]; //Bgr32 - Blue, Green, Red, empty byte //Bgra32 - Blue, Green, Red, transparency //You must set transparency for Bgra as .NET defaults a byte to 0 = fully transparent //hardcoded locations to Blue, Green, Red (BGR) index positions const int BlueIndex = 0; const int GreenIndex = 1; const int RedIndex = 2; const int AlphaIndex = 3; //loop through all distances //pick a RGB color based on distance for (int depthIndex = 0, colorIndex = 0; depthIndex &lt; rawDepthData.Length &amp;&amp; colorIndex &lt; pixels.Length; depthIndex++, colorIndex += 4) { //get the player (requires skeleton tracking enabled for values) int player = rawDepthData[depthIndex] &amp; DepthImageFrame.PlayerIndexBitmask; //gets the depth value int depth = rawDepthData[depthIndex] &gt;&gt; DepthImageFrame.PlayerIndexBitmaskWidth; pixels[colorIndex + BlueIndex] = 255; pixels[colorIndex + GreenIndex] = 255; pixels[colorIndex + RedIndex] = 255; pixels[colorIndex + AlphaIndex] = 0; //Color all players //Debug.WriteLine(player); if (player &gt; 0 ) { pixels[colorIndex + BlueIndex] = 0; pixels[colorIndex + GreenIndex] = 0; pixels[colorIndex + RedIndex] = 0; pixels[colorIndex + AlphaIndex] = 40; } } return pixels; } </code></pre> <p>The code of GetFirstSkeleton MEthod</p> <pre><code>Skeleton GetFirstSkeleton(AllFramesReadyEventArgs e) { using (SkeletonFrame skeletonFrameData = e.OpenSkeletonFrame()) { if (skeletonFrameData == null) return null; skeletonFrameData.CopySkeletonDataTo(allSkeletons); //get the first tracked skeleton Skeleton first = (from s in allSkeletons where s.TrackingState == SkeletonTrackingState.Tracked select s).FirstOrDefault(); return first; } } </code></pre> <p>The problem is here i have all the players UP TO 6 players detected by the depth image while only one by the skeleton tracking and i want to have only one in both, the same player.</p> <p>When i changed from player > 0 to player ==1 it didn't work because the player is not always with id 1.</p> <p>Any idea how to solve the matter ?!</p> <p>Thanks a lot, Michael</p>

    1. COMore information is required. You are going to have keep track of which skeleton belongs to which player more then likely. We need the code for `GetFirstSkeleton`. Looks like you can keep track of the player by looking at `PlayerIndexBitmask` which is likely between 1 and 6 since I believe the Kinect is limited to 6 player tracking.

    2. CO@Ramhound I added it to the code, thanks

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
