Hi everyone,
One of our graduate students is growing cells on membranes, cutting sections and then staining them. We are imaging these sections with the confocal microscope. Unfortunately, the membranes have pores and the Hoechst stain for nuclei seems to be sticking to the pores. Also, the sections aren't cut completely square so there's a gradient where the pores are visible in part of the image but not right across it due to the orientation. I've done a lambda scan and it's definitely the same emission spectrum as Hoechst. The intensity is similar but I want to get rid of the pores. I've tried a few background subtraction methods without success. I also tried FFT but the location of the pores isn't regular, it's random. Can anyone help? I've attached a sample image as JPEG.

Is this acceptable?

Hi Michael,
Just on my way home so reading this on my phone so can't view optimally but it looks good! More than acceptable. Will have a proper look when I'm back at work tomorrow. Thanks!

You might also want to erode or dilate the mask (depending on the
assignment of 0 and 255) to enlarge the mask around the objects of interest prior to combining the original image and the mask. That will help preserve the shape of some of the very low contrast objects. - Jim On 11/14/17, 12:21 AM, "ImageJ Interest Group on behalf of Jacqui Ross" <[hidden email] on behalf of [hidden email]> wrote: >Hi Michael, > >Just on my way home so reading this on my phone so can't view optimally >but it looks good!
