    Title Summary Primary Author Date
    2D Image Analysis
    Demonstrates image compression using biorthogonal 9/7 wavelet filters. Kevin Amaratunga 2002-08-08
    Capturing video data from I-Link cards
    This program is implemented in GUI environment of Matlab and invokes the data acquisition toolbox to capture video data from I-Link cards. It's also prepared some elementary features to edit the captured data and save it in the avi format. Ahmad Kolahi 2005-07-26
    Color Image Threshold Matlab Program
    I have made the MATLAB? source code for my color image thresholding method publicly available for research and testing purposes. It based my paper published at Optical Engineering: Y. Du,; C. Chang, and P.D. Thouin, "An Unsupervised Approach to Color Vid Yingzi Du 2004-08-11
    Correlation usig FFT
    Calculates the max correlation between a template and an image to find out if this template is existed in the image. Monther Alhamdoosh 2008-04-26
    Deinterlacing mixed video frames into normal video
    The graphical interface of this program is designed by Matlab GUI environment, and it has used Image Processing toolbox of Matlab to Deinterlace the mixed video frames into normal video frames. Ahmad Kolahi 2005-07-26
    Edge detection of greylevel image
    This program detects the edges of a greylevel image by using ant colony optmization algorithm. Chandan Nath 2009-05-10
    enhancing grayscale images
    contrast enhancement, histogram equalization, homomorphic filter. sanyam sharma 2003-10-01
    Freeman chain code
    Freeman Chain Code function Computes the Freeman chain code of a boundary. Chandan Nath 2009-05-07
    Frequency Domain Image Filters
    Apply ideal low-pass, ideal high-pass, gaussian low-pass, gaussian high-pass, butterworth low-pass, butterworth high-pass filters to gray-scale images in the frequency domain. Yingzi Du 2004-03-25
    Image Processing and tracing the Markers
    This program uses the mean square difference techniques to find the markers in the frames. The results are the Excel file of x-y coordinates of the traced markers. The program invokes some intelligent algorithms to find the markers positions. Ahmad Kolahi 2005-07-26
    Image registration
    The program performs image registration using the function fminsearch for minimizing the scale parameters. The success of the alignment estimated using the correlation criterion. Marios Vlachos 2005-11-08
    Image Rotation
    A very simple program to rotate an image by 90, 180 or 270 degrees. Sunny Jaiswal 2007-01-13
    k-mean Algorithm for segmentation of digital image
    k-mean algorithm is very handy in image segmentation. Here first the histogram is created and then the centriod is initialized, The number of clusters should be supplied by the user and the input image should be a greylevel image. Chandan Nath 2009-05-07
    Local Thresholding
    Find the local threshold of an image while dividing the image in 6 parts muhammad irfan 2006-06-23
    LP mode intensity distribution
    The intensity patterns for the LP modes. Namyoung Jang 2002-12-26
    Optical imaging .iv file reader
    ivimage.m is a simple function to read iv files produced in optical imaging experiments into MATLAB workspace. Dimitrios Giannikopoulos 2006-01-20
    A PIV post-processing and data analysis toolbox for Matlab Frederic Moisy 2006-09-08
    Synchronization of the cameras
    This program finds the same frames in the avi files that is captured with two cameras with different positioning and alignment, in other words it synchronize the two cameras frames. Ahmad Kolahi 2005-07-26
