how to apply convolution to two,two dimensional signals ..let me illustrate you in an elaborate way ..if I(x,y) is one two dimensional signal and H(x,y) is another signal varying in both x and y directions.how can i convolve both the signals

Answer 1

Simply using conv2()

You can also see the help for filter2(). Perhaps one of your matrices is a 2-D FIR filter for the data matrix.

[ashok]

can you tell me another way to find the convolution because i am unable to get the desired output from conv2(a,b)

[Anand]

How is the result of conv2 different from what you expect?

Maybe you want to use one of the options 'same' or 'valid'???
