Example
//Input image
CuviImage* gimg = new CuviImage(cuviSize(img->width,img->height),img->depth,img->nChannels);
gimg->upload(img->imageData,img->widthStep);
//Output Image
CuviImage* gout = new CuviImage(cuviSize(img->width,img->height),img->depth,img->nChannels);
//Choosing ROI
CuviROI roi = cuviROI(0,0,img->width,img->height);
//Creating a 5x5 Averaging Filter. User can also enter custom coefficients
CuviFilter* f;
cuviCreateFilter(&f,5,5);
cuviCreateFilterSpecial(f,CUVI_FILTER_AVERAGE);
//Applying filter 'f' on the image
cuvi::imageFiltering::imFilter(gimg,gout,roi,f);
