Question

My project is a computer vision java application which should implement the following :

1. A web interface through which the form entry+images(for example a student data) will be stored into a database(Mysql) & images into directory common to my java application.
2. Then the data & images can be retrieved from my java Gui application and I can perform the following operations of image processing through OpenCV.
3. Actually,I want to run the face detection on images retrieved and discard the false entries(no proper face).
4. Also the application user/admin can search an image based on text search(By Id) or By another reference image using face recognition.

I am well familiar with Java but the problem is that I need a guidance on how to organise it in a stepwise manner(links appreciated).OpenCv,Php and mySql are really messy.I know doing the openCV stuff within java is real overhead but i really want to do it.But If there is any suggestion to do it elseway please guide me.So any kind of help is a ray of hope for me.

• Thanks.

Answer 1

This sounds like a nice application. Here is what I would suggest you:

1- A web interface through which the form entry+images(for example a student data) will be stored into a database(Mysql) & images into directory common to my java application.

You will be able to easily create such application with Php and Mysql, just look for some tutorials on image uploading and php.

2- Then the data & images can be retrieved from my java Gui application and I can perform the following operations of image processing through OpenCV.

I’d recomend you using JavaCV. It is a wrapper over OpenCV which seems to work very well from some tests I have made. You get the flexibility of Java and the performance of C++ through a native bridge.

3- Actually,I want to run the face detection on images retrieved and discard the false entries(no proper face).

You can easily adapt the OpenCV face detection code to JavaCV: http://opencv.willowgarage.com/wiki/FaceDetection

4- Also the application user/admin can search an image based on text search(By Id) or By another reference image using face recognition.

The search by id is easily accomplished through some JPA or even JDBC connection. Now the similar face search is tricky. I’d point you to this link http://www.shervinemami.info/faceRecognition.html about face recognition in OpenCV.

I hope that helps.
