    <p>My goal is to calculate the calculation in each row of a 2D-image ( in the x-direction) After following the tip from Cory I am trying to use the ‘ConvolutionImageFilter’, and make a kernel with the Gaussian values I calculate before. I took a look to this example (http://www.itk.org/Wiki/ITK/Examples/ImageProcessing/ConvolutionImageFilter) and my question is how to include the values of the Gaussian filter to the kernel, I tried wit the code below and it compiles, but it seems the execution has no end when I update the convolutionFilter… Because of that I think that I am doing something wrong. My code is below and is not so much, if some can give some help I would appreciate that really a lot !!!!.</p> <pre><code>typedef itk::ConvolutionImageFilter &lt;ImageType&gt; ConvFilterType; ImageType::Pointer kernel = ImageType::New(); CreateKernel(kernel, Gaussian , 256); //Convolve image with kernel ConvFilterType::Pointer convolutionFilter = ConvFilterType::New(); convolutionFilter-&gt;SetInput(Li_itk); convolutionFilter-&gt;SetImageKernelInput(kernel); convolutionFilter-&gt;Update(); void Reg_image_v2::CreateKernel(Reg_image_v2::ImageType::Pointer kernel, double *Gaussian, unsigned int width) { ImageType::IndexType start; start.Fill(0); ImageType::SizeType size; size[0] = width; size[1] = 1; ImageType::RegionType region; region.SetSize(size); region.SetIndex(start); kernel-&gt;SetRegions(region); kernel-&gt;Allocate(); ImageType::IndexType pixelIndex; for (int i = 0 ; i &lt; width ; i ++){ pixelIndex[0] = i ; pixelIndex[1] = 0 ; kernel-&gt;SetPixel(pixelIndex,Gaussian[i]); } itk::ImageRegionIterator&lt;ImageType&gt; imageIterator(kernel, region); while(!imageIterator.IsAtEnd()) { //imageIterator.Set?? ++imageIterator; //operator++ increments the iterator one position in the positive direction } } // end createKernel </code></pre> <p>Antonio</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.
