#### Filter Implementation and Analysis | MATLAB Tutorial

Convolution and Filtering The mathematical foundation of filtering is convolution. The conv function performs standard one-dimensional convolution, convolving one vector with another: conv([1 1 1],[1 1 1]) ans = 1     2     3     2     1 A

#### Intensity Transformation and Spatial Filtering in MATLAB

Image scaling Using imresize MATLAB provides an inbuilt function imresize for rescaling an image. Let’s give it a shot! The syntax is: B = imresize(A, scale) Where, B = output image (scale * sizeof

#### Image Enhancement by Filtering in the spatial domain – Average Filters | MATLAB Tutorial

Image Enhancement When it comes to images, we are usually bothered by two different domains – spatial domain and frequency domain. Spatial filtering derives its name from the term “space”. One misconception that most

#### Color Spaces in MATLAB | MATLAB Tutorial

Color spaces – What do they mean? Color spaces are a lot like color maps in the sense that they are used to change the color scheme of a plot, a surface or even

#### Different Color Map and their transformation in MATLAB | MATLAB Tutorial

What is a Color Map? A Color Map is an m-by-3 matrix of real numbers between 0.0 and 1.0. Each row is an RGB vector that defines one color. The kth row of the Color Map

#### Introduction to Image Processing | MATLAB Tutorial

1           Overview “An image is worth a thousand words”. We rely heavily on images for interpreting large data sets and many-a-times, to make sense out of the world around us. In such a case,
