Hi,
I want to recognize silent speech words based on lip contour centroid key points .
Example : I have created MYSQL Database table column name "Words" , here 1. Hello , 2.How are You ,3. Nice to Meet You . etc.. after i have connected MySQL connection using matlab .Now i want to silent lip SVM(Support Vector Machine Speech Recognition) isolated word Pattern Matching? here reference link which i am following : http://www.ee.oulu.fi/~gyzhao/Download/Databases/OuluVS/lipreading-final-DC.pdf if any solution let me know .
Thanks

I'm sorry but to me this code looks totally random and disorganized, like you just threw together a bunch of unrelated chunks of code and hope they would somehow magically work together. Taking a (supposed) hue image and converting to YIQ color space? Huh? Taking both the Y and the blue channels and automatically thresholding them? Huh? Then taking the red channel and manually thresholding it? What? Calling imadjust on the Y channel? Totally unnecessary. Then threshold that? What? Measuring the filled binary image but then never doing anything with the results? Why? Then doing a bunch of morphological stuff on a binary image that came originally from the red channel and burning it into the original image. Why not just use bwboundaries and plot to put the outline into the overlay? Okay, that's just a jumble of code with no organized algorithm behind it.
Sorry to be so harsh but there is so much wrong with this algorithm that it isn't worth trying to fix. Like Walter said, we don't do algorithm development in this forum. I suggest you try to follow the algorithm in the paper rather than the one you listed here, which looks nothing like that.
One tip I can give is that for skin, the red channel has the least contrast between kips and surrounding skin, so you you probably shouldn't be using the red channel, at least not by itself.

More light is the best solution. Lack of light is giving no contrast to these lips.
