Re: automatic number plate recognition

I was talking with reference to the image on the poster. The image
consisted of a single vehicle's front side.

I am not sure about the robustness of edge detection. I would expect
many false positives and noise sensitivity. If you have written the
code for it, you can check your results.

Again, I am not aware of java packages that are available. U can use
the OpenCV C++ package which will give you most of the smaller routines
that you want, though I'm not sure if it will have functions for the
entire character segmentation and recognition.

This is just off the cuff - once you have segmented the title plate,
you can do character segmentation by first isolating individual
characters. This can be done by cropping subimages of each character
based on the white space (or black space) between black characters (or
white characters). Once you have individual characters, classification
can be done using PCA or ANNs.

I was going to use edge detection (i.e. vertical edge detection), is
this a good method or are there more efficient and accurate methods.
What method should I use for character segmentation.

Are there any classes or packages in java for these algorithms and
comparison stuff which I can use without coding from the
beginning..because I'm short of time..

Thanks,
