In image processing and statistics, in order to smooth a numerical data set it is to produce an approximation function which attempts to represent important random patterns in the input data, with no effort on the part of the observer. There are various methods to create smoothing in image segmentation. In the case of image smoothing, there is always a need for segmentation.


Image segmentation is often used in image processing. In such a case, the objective is to separate images of similar nature based on some criterion. It can be the shape of the object, its position and size and so on. The algorithm is implemented as follows:

The first step is to identify the objects in the image (image is called as the “model”). A grid is chosen, and all the points in the model are drawn on that grid. Then, the second step is to identify the shapes which will form the masks.

These points are then multiplied by the original image. This operation ensures that the new image closely resembles the original model. This smoothing is very much needed because if the points are not properly smoothed, you cannot calculate the original image. The method of smoothing is often called the normal map because the original image is mapped to the smoothed one.

An image smoothing algorithm takes as input a geometric representation of the image and then uses this geometric representation to map the points of the image onto a plane. This is done by assigning a value to each point in the original image. The point of intersection between the points is calculated, and the image is mapped onto the plane to make smooth edges.

Image smoothing algorithms are applied to images like paintings, photographs, video frames, etc. and are used for visual artifacts, noise, line patterns, and so on. While most of these algorithms are relatively simple, there are several others which are used for more complicated situations.

For example, while traditional image smoothing is usually done by simply computing the difference between the original and smoothed images, other types of smoothing methods are needed for high-resolution images. The first type of image smoothing is called the Gaussian filter which applies smoothing in a nonuniform way, making the images look more natural.

Another type of image smoothing is called thresholding where an image is sampled at a point, and the threshold is determined by the image. The image is sampled multiple times until it becomes blurred or the image is no longer visible. This is an alternative of high-quality image smoothing.

Image smoothing algorithms are implemented as algorithms. The first algorithm that was used to perform image smoothing in the previous paragraph is called the Gaussian filter. while the following algorithm is called thresholding.
