How can i do the sampling of a binary image?

Answer by Jan Simon on 31 Jan 2013

It depends on what "sampling" exactly means. Also "binary image" is not defined, so please post the inputs, the definition of the calculations and an example for the wanted outputs.

Answer by Image Analyst on 31 Jan 2013

Here's a way:

subsampledImage = binaryImage(1:2:end, 1:8:end);

How's that? It does exactly what you asked. It you want something more specific, you should explain further.

Answer by BHAVIN kakani on 5 Feb 2013

function sampling(x,step)

plot(x(1:step:end),'-o')

plot(abs(fft(x(1:step:end))))

It may help you out......If don't then do contact me with further details.

Who asked anything about the Fourier transform? Also, an image is usually 2D or 3D, not 1D, though it can be.
