How to Seperate Channels in Color Image in Matlab

The human visual system can perceive thousands of colors in a small spatial area, but only about 100 gray levels. Color contrast can be more dramatic than gray level contrast, and various colors have different degrees of psychological impact on the observer.  A subset of Physical images (Color Images) is multi-spectral images-those having more than one … Continue reading How to Seperate Channels in Color Image in Matlab

How to find Negative of Image in Matlab

How to find Negative of Image in Matlab

A negative is an image in which the lightest areas of the photographed subject appear darkest and the darkest areas appear lightest. This reversed order occurs because the extremely light-sensitive chemicals a camera film must use to capture an image quickly enough for ordinary picture-taking are darkened. Basically, In the Negative image, we subtract each … Continue reading How to find Negative of Image in Matlab

How to convert color image to binary image in Matlab

Digital Computers are being applied to the variety of applications because they can be programmed to handle almost any computational problem. Computer Imaging deals with interpreting images in a useful image, that is actually application dependent. A subset of Physical images (Color Images) is multi-spectral images-those having more than one local property defined at each point … Continue reading How to convert color image to binary image in Matlab

Arrays in MATLAB

Arrays in MATLAB

Array is a fundamental form that MATLAB uses to store and manipulate data. An array is a list of numbers arranged in rows or columns. There are two types of arrays Simples Array ( One-dimensional Arrays) Complex Array ( Two-dimensional Arrays) One dimensional array frequently represent vectors and Two-dimensional array represent matrices. Creating Vector The vector is created … Continue reading Arrays in MATLAB
