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 ... Read More

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 ... Read More

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 ...

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 ... Read More

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 ... Read More

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 ... Read More

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. ... Read More

In digital image processing, the auto cropping based labeling the connected components is a cropping technique in which different regions in an image are determined by using labeled connected component. After that the image is automatically cropped by extracting the surrounding area of each connecting component. The main advantage of ... Read More

Histogram equalization is a method used in image processing to improve the dynamic range of the histogram. This mathematical technique is widely used for enhancing the contrast of an image in digital image processing. This technique provides a wider and balanced distribution of pixel values in the image. Histogram equalization ... Read More

What is a Computer? A computer is an electric device which is developed by Charles Babbage in 1822. It takes input data from the input devices, stores and process it, and produces output in the output devices. The processing is done by the Central Processing Unit. It is ... Read More
