A demo program of image edge detection using ant colony optimization.
IMComp is an Image COmpression Software based on MATLAB used to compress various JPEG images. This software is primarily useful for compressing images which are being taken with the help of Digital Cameras and Mobile Phones
Given an aerial image of a city block this program extracts all objects deemed "red". It is simple and short and should help those wanting to get a foot in image processing.
finding mean vector of RGB image
This util reads in data and meta-data from ATL/Philips ultrasound scanners, stored in XIF (eXcellent Image Format) files.
It only reads the most commonly used elements from the meta-data (Scanlines, Samples, Frame Rate, Frames and...

A demo for image segmentation using iterative watersheding plus ridge detection.
convertion of image to black and white image using slicing image without background.
we have to inter two thresholdvalues for doing that...
Butterworth Bandpass Filter
This simple function was written for my Digital Image Processing course
at Eastern Mediterranean University taught by
Assoc. Prof. Dr. Hasan Demirel
for the 2010-2011 Spring Semester
K-means image segmentation based on histogram to reduce memory usage which is constant for any image size.
Image can be compressed using KL transform the code demonstrates the method
zooming a given image by a given positive factor can be done..
copy nearest_neighbor_zoom.m file and the image file that should be zoomed to your work directory.
if the name of the image file is image.jpg and the zooming factor needed is...
the program is for pseudocolor image processing, it can convert a grayscale image to color. The color may not be accurate but quite useful for certain applications.
Extracts the edges of a color image without converting it to grayscale.
Changes in color are detected even when the grayscale color of two pixels are the same. The edge strength is typically greater or equal to the magnitude obtained by...
I did it mainly because matlab did not give the detailed code for thinning a image. So I used the same algorithm to present how thinning algorithm used in matlab and I wish to give a detailed one here
using image processing techniques ,first change the RGB image to gray scale than applying function to calculate the percentage of white color in an image.
In this code first the color image is converted into grayscale image using the function rgb2gray().
And then a thresholding method is used to convert the image into binary format..
Calculates multifractal spectrum of a binary image based on the ideas in the paper by Posadas et al., Soil Sci. Soc. Am. J. 67:1361-1369, 2003.
