On this page, research scholars can get to know about developing their Digital Image Processing Projects Using Matlab functions for various processing techniques. A digital image is the composition of a finite number of picture elements called pixels. Also, it is represented as 2D functions with f(x, y) spatial coordinates in the form of discrete mathematical representation. Majorly, the Image is made up of any of the following,

• 4D and above hypervoxels – Represents hyper-volume elements
• 3D voxels – Represents volume features
• 2D pixels – Represents picture features

In general, digital image processing is the method of manipulating the digital images in the digital system for generating digitalized enhanced images. It is also one of the main applications of signal processing for working with 2D video or images. Here, we have given you the typical types of practice involved in image processing.

How Images Processed? 

• Image processing is done by a computerized machine where human views the outcome is known as automatic analysis.
• The processing of Images done by both machines and humans is known as semi-automatic analysis.
• The processing of Images done by humans is known as manual analysis.
