The note explains in detail how to apply the Matlab 2-dimensional FFT for filtering of two-dimensional signals, e.g. images.
It is shown how to connect the output from fft2 to the actual Fourier transform of the signal, and in particular how transfer functions of simple filters may be coded.

Design and content (texts, pictures, documents) are administered separated from each other. The working environment is very similar to a simple text processing. The system operates intuitively.
plotRGB allows quick plotting of an overlay of three grayscale images with possible custom scaling of the R, G and B intensity ranges
grayscale ranges are normalized for RGB plot
Use this plugin instead of tiresome saving images from the internet and uploading them to your blog posts. You learn the value of this grabber, e.g. when you need to move your old non-WordPress site with many pictures to the WordPress-based.
G-Book features: duplicate post prevention, HTML blocking, emailing admin errors, emailing admin entries, SSI support, images support for the form, checking for valid email address, URL blocking and banning entries.
WP Smart Image II gives to you a whole control over the images you wish to show with posts and pages (e.g. the index of a website). This plugin combines the best image management functionalities in WordPress and turn their handle to do a very easy...
Compare two images using the root mean squared analysis. A result close to 0 means a good match.
Running this python script will download all lolcat images from icanhascheezburger.com to the current folder. Download will start from the oldest image. Images are collected into subfolders lolcat0, lolcat1 etc, each containing 300 images. The...

Fading Images 2 enables multiple images to be displayed within a single area. The transition between images is a very smooth fading effect, the speed of which can be varied by changing the parameter values.
Floating Images II animates any image (or block of HTML) up and down the browser window, like an elevator, and stays in view even if the user scrolls the page.
This script generates an efficient and elegant rain/snow effects.
The effect is created without the aid of images. You can toggle between rain and snow effect with the change of one variable.
A fast vectorized implementation of the ncc that handles color (3 channel) images as well as gray level.
The algorithm for colored images is based on the ncc formulation for vector valued functions.
Note: A bug that I found in the...
Usage: I=mi(A,B), where A and B are equally sized images/signals.
Function hist2 (included) is used to determine the joint histogram of the images/signals. All histograms use 256 bins.
Assumptions: 1) 0*log(0)=0, 2) mutual...
Simple Matlab Code for Neural Network Hebb Learning Rule.
It is good for NN beginners students. It can be applied for simple tasks e.g. Logic "and", "or", "not" and simple images classification.
This script applies the Maximum Correlation Cross on SST images, to estimate the superficial ocean currents
