    <p>First of all: I am quite new in programming Kinec via MS Visual Studio ... so sorry if my question is a little bit stupid.</p> <p>I want to detect if my hand contacts the upper part of a quadrant; for that I programm:</p> <pre><code>Image&lt;Gray, Byte&gt; HandImage = GetThresholdedImage(ref bgrImage, (int)hueHand); Image&lt;Gray, Byte&gt; depthImageBin = depthImage.ThresholdBinary(new Gray(30), new Gray(255)); List&lt;MCvBox2D&gt; DangerAreas = new List&lt;MCvBox2D&gt;(); List&lt;MCvBox2D&gt; HandAreas = new List&lt;MCvBox2D&gt;(); // build list of object rectangles DangerAreas = ProcessObjectContours(bgrImage, contoursDepthObjects, contoursHand, objectSize); // build list of hand rectangles HandAreas = ProcessHandContours(bgrImage, contoursHand, contoursDepthObjects, handSize); </code></pre> <p>whereby the values <code>objectSize</code> and <code>handSize</code> define the minimum-limit of the objects.</p> <p>so far all works well, I see the shapes on the display. If the two contures match, they merging.</p> <p>But I want that the software annouce when my hand (<code>HandAreas</code>) touch the object (<code>DangerAreas</code>) at a defined region.</p> <p>I tried to solve the problem with <code>MatchShapes</code>:</p> <pre><code>contoursDepthObjects.MatchShapes(contoursDepthObjects[0], contoursHand[0], Emgu.CV.CvEnum.MATCH_CONTOUR_TREE_METHOD.CONTOUR_TREES_MATCH_I1, 2); </code></pre> <p>but in this form <code>MatchShapes</code> is not accepted, because of errors. So two questions: is this the right way to detect when my hand touch the danger area, and if yes how is it correct handling of method <code>MatchShapes</code>?</p>

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.
