The Lloyds algorithm of lloyds.m - broken?
Hello, I am a little bit puzzled about whether the Lloyd/k-means algorithm in the MatLAB function in lloyds.m actually works in either R2009b or R2010a (atleast). When executing the example available in doc, or at: http://www.mathworks.com/access/helpdesk/help/toolbox/comm/ref/lloyds.html The results i get by... 5 Apr 2010 16:06

Facial aging project help
I'm doing a facial aging project. I wanted the user to click on certain control points on the 20 year old image and then wanted the program to to warp certain features downward to show geometrical facial changes.The displacement will have to be embedded into the code. How do I go about it?..Im new to MATLAB...Can I ... 5 Apr 2010 16:06

Pattern Recognition
I am designing a system using a robot in such a way that the Robot will pick up the tool when the camera sends the picture of the tool in its memory. In this, I need to use pattern recognition using Matlab. I have two tools to recognize. First my question is: What kind of webcam should I use? Should I use the ... 5 Apr 2010 17:13

M-QAM and M-PSK
hi, I need a matlab code to simulate the Bit error rate vs. Eb/No for BPSK, QPSK and 8-PSK as well as, 4-QAM, 16-QAM and 64 QAM. The modulation should be done using "qammod" and "pskmod" functions and the additive white gaussian noise should be added using "normrnd" function with zero mean and segma depending on Eb/ N... 6 Apr 2010 08:34

SNR of signal
Hi guys. I'm currently working on a sound project which requires me to reduce noise from noisy speech signal. I'm using wav files taken from the NOISEUS database which provides the clean speech and the noise currupted signal (Clean speech + Noise) in different SNR of 15 10 5 and 0 dB. And after reducing the n... 5 Apr 2010 22:48
