Meeting - December 9, 2011

Due to the Christmas break, we will not be meeting for about a month.  We will meet up again as soon as Dr. Zheng gets back from vacation and we start school again.

During the meeting Dr. Zheng looked over our progress reports and made a few suggestions about the formatting.  He suggested we revise them and send them to him for final approval.

Dr. Zheng also said that next semester we will be working more actively in the programming of more features.  He said that Jacqui and Kaitlyn could start working on programming a couple features over break.

I hope everyone has a great break!  Have a Merry Christmas and a Happy New Year!!!

Progress Update

I have read through the color features papers.  I have also completed the survey sent to us by the Computing Research Association.

The mid-year progress report is what I am working on now.  I have finished the first draft.  I will be sending this in as soon as I finalize it.

Preparation and report

I can't believe how busy we've all been the past couple weeks, what with finishing projects and finals coming up. I'm currently completing my CREU midyear progress report. It will be finalized tomorrow after Dr. Zheng takes a look at them at our next meeting. Also, finished reading the papers Dr. Zheng sent us on color features.

Progress Update

I have finished reading all of the papers (excluding the color features papers that were recently sent).  Since I received the program, I have been reviewing the code to understand it better.
I also reviewed and submitted changes on the ITNG paper submission.

I will continue to go through the code and I will make some changes so that I can start testing it.  I will be comparing my results with our previous results as well as the results received by the use of the DCT method.  I will also read the color features papers so that I can get ideas in order to implement color features within our code when we are ready.


Matlab Code Meeting - Monday, November 14

Yang sent Kaitlyn and Jacqui the commented code.  During the meeting, Yang discussed the flow of the project, the changes Kaitlyn and Jacqui needed to make to test different images to try to receive better results.  He also discussed the naming method for the photographs.

Yang also showed us a flow chart he created that was based on the program code.  It showed the structure of the code from multiple files and what those particular files are being used for.

Meeting - Friday, November 4

We discussed the paper we were submitting to ITNG 2012.  We reviewed some of the methods we were using in our program as well as some of our early results.  As of now our results are showing more improvement in copy-move forgery than the DCT method.

Dr. Zheng said he would be sending a couple more papers on color features for Jaqui and Kaitlyn to read.  We also agreed to meet again to go over the program code.

Progress Update

I have finished the matlab tutorial and went through some of the code that Yang shared with us.  I  also re-read the DCT paper to better understand our method.  

We were unable to have a meeting last Friday, however, I talked with Dr. Zheng who said he would send some more papers regarding the project.  I have read "A Study on Features for the Detection of Copy-Move Forgeries" by Christlein et al.  I will continue to read the other documents.

Progress Update

I was unable to attend the meeting last Friday, so I met with Dr. Zheng on Thursday. He told me about the progress that Yang has made using DCT. Waiting to see some of the code, maybe read a report on it.

On Wednesday, Yang and I attended a seminar on MATLAB and parallel computing. It was quite interesting, and even as a new user of MATLAB, it wasn't entirely over my head.

Second Meeting

Second Meeting on September 8, 2011

During our meeting, Dr. Zheng said to make sure to understand the DCT paper.  We will be using the DCT procedure to create our program, however, instead of using DCT we will be using the wavelet-based detection.  Later in the project we will also look at colors.

Jacqui and Kaitlyn will start receiving small tasks to begin getting involved in the programming part of the project.

We will be meeting every other Friday.

Progress Update

I have read through the articles "Wavelet-Based Multiresolution Features for Detecting Duplications in Images", "Improved DCT-based detection of copy-move forgery in images", and "A Survey of Copy-Move Forgery Detection Techniques."  I still plan on reading more information based on wavelet detection.

I have also been working on the Matlab tutorial.  I have been working with the interactive interface the most, however, I have started working on simple programs.  While working with the interactive interface I was dealing with matrices, variables, functions, logical operators, the colon notation, and other features.  While working with programs, I worked on for loops, while loops, branching, assignment, and I have started on recursion.

Progress Update

I read the articles last week that Dr. Zheng sent us. The "Wavelet-Based Multiresolution Features for Detecting Duplications in Images" article makes it clear why we need MATLAB for this project.

The other day, I reviewed the code Yang Wang provided for us. Since I am still unfamiliar with MATLAB, I ran a couple of the M files just to see what they would do. After providing an image for one of them, I got it to spit out a couple numbers. Questions pending; I'll go over the code some more this week.

NMT CREU Website

Check out our website at

First meeting

First Meeting on August 26, 2011

Dr. Zheng introduced the project and the deadlines in which we need to fulfill. We need to create a website to meet our first deadline in September. We also need to start researching previous work on copy-move forgery detection as well as Matlab.

We plan to attend a technical conference in Las Vegas next April. Jacqui and Kaitlyn will also be attending the  Grace Hopper Celebration of Women in Computing (GHC) conference next year.

The final topic is posting our work weekly on the blog.
