title: OpenCV GPU HOG detection
body: <p>I'm using Windows 7 64bit, visual studio 2010, opencv 2.4.2.</p>
  
  <p>I'm trying to use GPU hog detector.</p>
  
  <p>For now I can use my own CPU hog detector (my trained version).</p>
  
  <p>My hog has cellsize of <code>Size(4,4)</code>.</p>
  
  <p>However, in opencv/modules/gpu/src/cuda/hog.cu, it states that</p>
  
  <pre><code> // Other values are not supported
    #define CELL_WIDTH 8
    #define CELL_HEIGHT 8 
  </code></pre>
  
  <p>or, in opencv/modules/gpu/src/hog.cpp, in the </p>
  
  <pre><code>cv::gpu::HOGDescriptor::HOGDescriptor( ... ) { ... CV_Assert(cell_size == Size(8, 8)); ... }
  </code></pre>
  
  <p>I think this is the reason why my program crashes. However I don't want to use cell size 8. How can I chage it to 4?</p>
