The above image has two rows and two columns, we will first zoom it row wise.Row wise zoomingWhen we zoom it row wise, we will just simple copy the rows pixels to its adjacent new cell.Here how it would be done.1 1 2 2 3 3 4 4As you can that in the above matrix, each ...
This image also has less details, but it is not true blurring.Because in zooming, you add new pixels to an image, that increase the overall number of pixels in an image, whereas in blurring, the number of pixels of a normal image and a blurred image remains the same....
In the current digital era, images have become one of the key channels for communication and information. There are multiple platforms where digital images are used as an essential identity, like social media platforms, chat applications, electronic and print media, medical science, forensics and cr...
The general process of filtering and applying masks is consists of moving the filter mask from point to point in an image. At each point (x,y) of the original image, the response of a filter is calculated by a pre defined relationship. All the filters values are pre defined and are a...
Digital image processing deals with manipulation of digital images through a digital computer. It is a subfield of signals and systems but focus particularly on images. DIP focuses on developing a computer system that is able to perform processing on an image. The input of that system is a ...
(Digital Image Processing - Gonzalez, Woods - 2nd Edition) Or in other way we can define spatial resolution as the number of independent pixels values per inch.In short what spatial resolution refers to is that we cannot compare two different types of images to see that which one is clear ...

In our case the image is 8bpp, so levels of gray are 256.The minimum value is 0 and the maximum value is 225. So the formula in our case iswhere f(x,y) denotes the value of each pixel intensity. For each f(x,y) in an image , we will calculate this formula....
Learn the fundamentals of Digital Signal Processing with our comprehensive tutorial covering key concepts, applications, and techniques.
Filters The concept of filter in frequency domain is same as the concept of a mask in convolution. After converting an image to frequency domain, some filters are applied in filtering process to perform different kind of processing on an image. The processing include blurring an image, sharpening...
