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 …
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 …

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 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 …
