An image is worth a thousand words, but sometimes this becomes difficult to express in text. Thus, there are special filters that can enhance the look of a picture or a video. One such tool is a hybrid median filter.

The Hybrid Median Filter for Noise Removal in Digital Images is described as a combination of several algorithms such as median filter, AO and B-spline. This filter is used to smooth the edges of a picture. A common usage of this filter is for Image Enhancement.

A MATLAB assignment help module is provided for such filters. The module analyzes an image to discover the boundaries of objects. It is able to match edges from another image by applying the appropriate filter.

Most of the time, filters are applied in MATLAB by attaching a series of algorithms to it. But when it comes to a MATLAB assignment help module, it is very important to have a basic understanding of these algorithms. It is also important to know their usage so that the MATLAB help module can be applied properly.

It is the most commonly used algorithm for calculating the magnitude of the nuclide. It is called Unsharp Mask, which was invented by Andrew Newman in 1975. This filter is also used to determine the intensity of an object in a mathematical equation, so it is named as an inverse function.

In this function, the term “degree” is also included. It means the number of angles in the masking that are not relevant to the area under the curve. In order to remove these ugly edges, an additional method is applied.

The above mentioned method is called the Irregular Filter. It is used in the median filter and is composed of two subfilters. A cutoff radius is taken to decide which path should be taken. This function is named so because of its irregular shape.

The second filter in this filter chain is the Gaussian Option, which is considered as the flat option. It is chosen to be the ‘sharpness’ in the linear or logarithmic filter. The top path gets processed and becomes the sharpness in this filter. The middle path is divided into four parts, which are called centers, by starting with the first and continuing on with the second one.

The black and white region of the grayscale image is set to the non-linear black points. The grayscale region with the blue colors is included in the non-linear grayscale curve. The gray points of the image are shown by the symbol v.

This module explains how to use this filter in MATLAB. A series of curves can be created by dragging the desired regions of the image. The solutions can be displayed by choosing the Equation option.

The solution of the graphic is transformed using the Gaussian Nondistribution and is then distributed to the other curves. After the filtering, a third Gaussian Nondistribution is added in order to remove the non-linear features. Finally, the upper path is modified and it becomes a square Gaussian Nondistribution.

MATLAB help module provides tools in performing these filters. To learn more about this type of filter, I suggest you visit the website below.
