Erosion and Dilation in Digital Image Processing

Morphological Image Processing: It deals with extracting image components that are useful in representation and description of shape. It includes basic morphological operations like erosion and dilation. The outputs of morphological processing generally are image attributes. Erosion and dilation are fundamental morphological operations. But before understanding these, let us see some basics which are essential […]

Digital Image Processing and its applications

Digital Image Processing

What is digital image processing? As evident from the question, digital image processing is the processing of images that are digitally stored using a computer. In other words, we can say that “Digital Image Processing refers to the processing of digital images by means of a digital computer.“ Now that we have understood that what

Sampling and Quantization in Digital Image Processing

Digital Image Processing

Need of Sampling and Quantization in Digital Image Processing: Mostly the output of image sensors is in the form of analog signal. Now the problem is that we cannot apply digital image processing and its techniques on analog signals. This is due to the fact that we cannot store the output of image sensors which

Fundamental Steps in Digital Image Processing

Digital Image Processing

1. Image Acquisition: In image processing, it is defined as the action of retrieving an image from some source, usually a hardware-based source for processing. It is the first step in the workflow sequence because, without an image, no processing is possible. The image that is acquired is completely unprocessed. In image acquisition using pre-processing such

Image Restoration and Image Degradation Model

Digital Image Processing

Image restoration is the process of recovering an image that has been degraded by some knowledge of degradation function H and the additive noise term . Thus in restoration, degradation is modelled and its inverse process is applied to recover the original image. Objective of image restoration: The objective of image restoration is to obtain
