Mexican hat filter in Genome analysis

[Artem_Y_Intel]

Hi,

Could somebody point me to a way in which I could apply a Mexican hat filter to an image using IPP?

Such filter is usually used for attenuating low and high frequencies that makes the image smoother and the edges stronger.

In my case it is necessary for further object detection on image analysis stage of Genome software.

Are necessary functions have been implemented in IPP? In this case does somebody know of a piece of code floating around that can do this?

Any clarifications would be very usefull.

Thanks.

We may do not have exactly 'mexican hat' filter function in IPP but we do have gaussian and laplacian filters. You may also be interested with IPP bilateral filter.
