    <p>I'm currently doing a research on Automatic traffic sign detection using SIFT algorithm for final year University project. I am using OpenCV and at the moment I have reached until find Descriptors of an image. I am storing this SIFT features in a list using following code,</p> <pre><code>vector&lt;Descriptor&gt; m_keyDescs; m_keyDescs.push_back(Descriptor(descxi, descyi, fv)); </code></pre> <p>Now I want to use this features to compare with a new image and I want to recognize whether the new image is same as the previous image. But I have no idea how to use this features that stored in a list to identify new image. How can I retrieve this stored list and compare with newly created Descriptors of an image??</p> <p>I am so glad if you can help me as I'm new to OpenCV. :)</p> <p>I have defined Descriptor class as,</p> <pre><code> class Descriptor { public: float xi, yi; vector&lt;double&gt; fv; // Feature vector Descriptor() { } Descriptor(float x, float y, vector&lt;double&gt; const&amp; f) { xi = x; yi = y; fv = f; } }; </code></pre> <p>Thanks for your kind consideration...</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.
