Log Polar transformation of Image

[EmmanuelGg]

Since the log polar is not supported by imaq, i am writing my own c function to do the same. Since we need to it on the spectrum, i am getting large values. If i do the FFT on it and try to display the image by darawing functions, it is not able to display. Need help or comments

Whether need to do some scaling before doing the FFT on the Log Polar transformed image

EmmanuelGigy,

Thanks for using our discussion forum. You are correct about there not being a supported log-polar function in IMAQ. In fact, if it was supported it would most likely be included with our Vision Development module instead. If you are having trouble displaying your image, you may want to try some of the examples that install with IMAQ for Visual C. you can find these in Program Files>>National Instruments>>NI-IMAQ>>Sample>>Display. Hopefully these examples should help you out.
