Applies the bilateral texture filter to an image

dst = cv.bilateralTextureFilter(src)
dst = cv.bilateralTextureFilter(src, 'OptionName', optionValue, ...)

Input

• src Source image whose depth is 8-bit uint8 or 32-bit single

Output

• dst Destination image of the same size and type as src.

Options

• FR Radius of kernel to be used for filtering. It should be positive integer. default 3
• NumIter Number of iterations of algorithm, It should be positive integer. default 1
• SigmaAlpha Controls the sharpness of the weight transition from edges to smooth/texture regions, where a bigger value means sharper transition. When the value is negative, it is automatically calculated. default -1
• SigmaAvg Range blur parameter for texture blurring. Larger value makes result to be more blurred. When the value is negative, it is automatically calculated as described in the paper. default -1

It performs structure-preserving texture filter. For more details about this filter see [Cho2014].
