Detailed Description

OpenCV Smooth Filter.

Smooths the image in one of several ways.

Parameters:

Parameters:

	smooth_type	Type of the smoothing: CV_BLUR_NO_SCALE - linear convolution with param1xparam2 box kernel (all 1’s) CV_BLUR - linear convolution with param1xparam2 box kernel (all 1’s) with subsequent scaling by 1/param1·param2 CV_GAUSSIAN - linear convolution with a param1xparam2 Gaussian kernel CV_MEDIAN - median filter with a param1xparam1 square aperture CV_BILATERAL - bilateral filter with a param1xparam1 square aperture, color_sigma=param3 and spatial_sigma=param4. If param1=0, the aperture square side is set to cvRound(param41.5)2+1.
	param1	The first parameter of the smoothing operation, the aperture width. Must be a positive odd number (1, 3, 5, ...)
	param2	The second parameter of the smoothing operation, the aperture height. Ignored by CV_MEDIAN and CV_BILATERAL methods. In the case of simple scaled/non-scaled and Gaussian blur if param2 is zero, it is set to param1. Otherwise it must be a positive odd number.
	param3	In the case of a Gaussian parameter this parameter may specify Gaussian standard deviation. If it is zero, it is calculated from the kernel size: sigma = 0.3 (n/2 - 1) + 0.8, where n = param1 for horizontal kernel and param2 for vertical kernel
	param4	In case of non-square Gaussian kernel the parameter may be used to specify a different (from param3) sigma in the vertical direction.
