Lbp using median filter
WebDescription. example. J = medfilt2 (I) performs median filtering of the image I in two dimensions. Each output pixel contains the median value in a 3-by-3 neighborhood … The median filter is a non-linear digital filtering technique, often used to remove noise from an image or signal. Such noise reduction is a typical pre-processing step to improve the results of later processing (for example, edge detection on an image). Median filtering is very widely used in digital image processing because, under certain conditions, it preserves edges while removing noise (but see the discussion below), also having applications in signal processing.

Since the median filter is directly affected by the kernel size, too small is not enough for a good median estimation and too big will catch artifacts in the median filter. After playing with different kernel sizes, 11 was best.

The median filter is also used to preserve edge properties while reducing the noise. Also, the smoothing techniques, like Gaussian blur is also used to reduce noise but it can’t preserve the edge properties.
