Difference between Mobile IP and GSM
Mobile IP extends its hand to communicate between devices that are wirelessly connected. Mobile Internet Protocol (IP) comes under the fourth layer of the OSI model called the Network layer. GSM comes under the second layer which is a physical layer of the OSI model. In GSM, the geographic area is divided into hexagonal cells, each of whose side is determined by the transmitter's strength and load. A base station with a transceiver and an antenna is located in the middle of the cell. What is Mobile IP? Mobile IP is a protocol that gives a set of rules to ...
Read MoreDifference between IMAP and SMTP
When it comes to e-mail communication, two primary protocols play a significant part within the handle - IMAP and SMTP. Whereas both of the protocols are essential for email communication, they serve diverse purposes and have different functionalities. Understanding the distinction between IMAP and SMTP is pivotal for anybody utilizing email services or creating mail clients. In this article, we are going investigate the contrasts between IMAP and SMTP, including their definitions, functionalities, and utilize cases. IMAP IMAP stands for Internet Message Access Protocol. IMAP permits clients to oversee their e-mail messages on the server, instead of downloading them to ...
Read MoreCreate Array of Zeros in MATLAB
In MATLAB, the variables are typically stored in the form of a matrix or array. Sometimes, we require a matrix or array of zeros to perform a specific operation. Therefore, MATLAB allows us to create a matrix or array of zeros. For this task, we can use MATLAB's built-in functions or manual methods. In this article, we will learn different methods to create a matrix or array of zero with the help of example programs in MATLAB programming. Array of Zeros using `zeros()` Function in MATLAB MATLAB provides a built-in function named `zeros()` to create a matrix ...
Read MoreChange Background of Color Image into Grayscale in MATLAB
We can obtain grayscale color by setting RGB values to 128. This means all color channels will have the same intensity values. The following MATLAB program illustrate the code for changing the background of a color image into grayscale. Example %MATLAB program to demonstrate changing color background into grayscale % Read the input colored image img1 = imread('https://www.tutorialspoint.com/assets/questions/media/14304-1687425236.jpg'); % Display the input color image subplot(1, 2, 1); imshow(img1); title('Original Image'); % Create a binary mask of the background BGMask = img1(:, :, 1) == img1(1, 1, 1) & ... ...
Read MoreCheckbox in MATLAB App Building
MATLAB provides an integrated app building toolbox that we can use to create a graphical user interface based app without writing any kind of code. Hence, MATLAB allows users to create professional applications by just drag and drop facility. After that the user can write a MATLAB code to define the behavior of the app options. As mentioned above, this article is primarily meant for creating a user interface in the application which provides a list of options from which a user can select any number of choices. This user interface is referred to as checkbox. A checkbox ...
Read MoreAutomatically Plot Different Color Lines in MATLAB
The different color lines in a plot allows us to plot and distinguish multiple data sets on a same plot area. MATLAB provides various built-in functions to assign different colors to different plot lines automatically. To automatically control the color of plot lines, we can use the following two MATLAB functions: Automatically Plot Different Color Lines using Hold Option In MATLAB programming, we can use the “hold” option to automatically plot different color lines. Syntax hold on; The following MATLAB program explain the use of “hold” function to plot lines of different color. Example % ...
Read MoreCombine two images in MATLAB
MATLAB allows us to combine two images through various methods like image fusion, image join, image concatenate, image overlay, image blending, etc. In this tutorial, we will explore all these techniques of combining two images. Combine Two Image in MATLAB using `imtile()` Function In MATLAB, we can combine two images by using the `imtile()` function. This function allows us to arrange our multiple images in a tiled layout. Syntax To combine two images, the `imtile` function takes the following syntax: img = imtile({img1, img2}, 'GridSize', [1, 2]); Now, let us see the implementation of the ...
Read MoreBalance Contrast Enhancement Technique in MATLAB
In digital image processing, the contrast enhancement is a crucial technique used to improve visual quality of an image. The contrast enhancement technique adjusts the intensities of pixels to increase the range of brightness levels and highlights the differences between bright and dark regions of the image. MATLAB provides various contrast enhancement techniques, but in this article, we will confine our focus to understand the balance contrast enhancement technique, and will see its implementation in MATLAB programming. What is Balance Contrast Enhancement? In MATLAB, the balance contrast enhancement technique is a modern method to improve the contrast ratio ...
Read MoreCalculate Complex Conjugate Transpose in MATLAB
The Complex Conjugate Transpose is a mathematical operation performed on a matrix of complex numbers. It is also known as Hermitian Transpose of Matrix. In this operation, first the transpose of the matrix is taken and after that the conjugate of each element of the matrix. For example, if a there is a complex matrix M, then the complex conjugate transpose of this matrix will be M* that is obtained by taking transpose of M and then replacing each element with its complex conjugate. The complex conjugate of a complex number is simply determined by changing the sign of ...
Read MoreAutomatically Maximize an Image in MATLAB
MATLAB programming allows us to automatically maximize an image for better visibility. For this, we can use the “figure” function with some arguments which described in the following syntax. Syntax figure('units', 'normalized', 'outerposition', [0 0 1 1]); The “figure” command with all these parameters automatically maximizes an image. The following MATLAB program demonstrates the implementation of a code to automatically maximize an image. MATLAB Program Example % MATLAB program for automatically maximize an image % Read the input image img = imread('https://www.tutorialspoint.com/assets/questions/media/ 14304-1687425236.jpg'); % Replace 'your_image.jpg' with the path to your image % Display the original image in ...
