Can I Do These Pre-Processing On Image Before Applying Uniformlbp

bitwise_not(src, src);
	
	// matrices used
	Mat dst; // image after preprocessing
	
	
		//frame=src;
		cvtColor(src, dst, CV_BGR2GRAY);
		GaussianBlur(dst, dst, Size(7, 7), 5, 3, BORDER_CONSTANT); // tiny bit of smoothing is always a good idea
		threshold(dst, dst,0, 255, CV_THRESH_BINARY | THRESH_OTSU);
