image matching

hi all,
how can i use the correlation function to find the best match of the image that i have with the templates that are there in a library? can somebody explain an easy way to achieve this?

Hi members of this group:
Can any body tell me how to generate PN sequence as an input to a
non-coherent Binary FSK transmission system.
Matlab code please.

Thanks,

hi,

For PN Sequence genearation we have one block in
simulink.You can use it for getting the Pn sequence
and send the output to the m-file by saving the output
of simulink in 'to workspace'.

Refer to Spread Spectrum Systems by Richard Dixon. It has a flow chart and associated data tables required for implementing a PN sequence generator. You will be getting a discrete sequence now. And then you have to write a code to simulate a continuous signal operating at particular frequency, to get a continuous PN sequence signal running at the required frequency.

Good Luck!
