We present DenoisEM: an interactive and GPU accelerated denoising plugin for ImageJ that ensures fast parameter tuning and processing through parallel computing. Advanced denoising techniques can alleviate this, but tend to be less accessible to the community due to low-level programming environments, complex parameter tuning or a computational bottleneck. Moreover, large 3D EM datasets typically require hours to days to be acquired and accelerated imaging typically results in noisy data. This has caused an explosion in dataset size, necessitating the development of automated workflows. Then on the “Sat layer”, choose Filters->Re-Show Gaussian Blur and use a radius of about 11.The recent advent of 3D in electron microscopy (EM) has allowed for detection of nanometer resolution structures. Now, for the final touch, select the “Ink layer” then choose Filters->Blur->Gaussian Blur and use a radius of 1 or 2. Meanwhile, if you want to add lighter shadows, you just need to follow the same steps but you will only have to choose white shades instead of black shades. Then move that layer to just above your Ink layer and select Layers->Merge Down. Then select Colors->Levels and set the Output Level on the right to somewhere around 40. Then choose Colors->Threshold and find the point where you can see the details you’ve been missing. It will have the portions of the original image that correspond to the blacks in your Ink layer. Name the resulting floating layer “Shadows”. Then go to the Original layer and then select Copy and Paste. With the Select By Color tool, click on any black part of your image. Turn off your Color and Sat layers by clicking on the “eye” icon. To make that missing part show, we can add a layer of shadow. ![]() There are times when your image looks like it has a lot of black shadows where there should be a fabric or something depending on the image used. If you think the nose and the eyes look okay now, then click OK. Then click the center of the pupils (left and right eye) and click 3 to 4 times, each time the eye should become a little bigger. Be sure not to move too much to the nose as it may remove your distorted nose.īy now the eyes should be looking normal again, we’re now going to make them a bit bigger. Drag the mouse slowly over the left eye towards the nose and do the same on the right. If your eyes became a bit too much distorted, use the “Remove” option in the dialogue (which should still be shown). ![]() Don’t click OK yet as we will also work with the eyes. Be careful not to move too much of the nose into the eyes. Now start at the top of the nose in the middle: drag the parts of the top nose a little to the left and a little to the right. You can increase the radius if you have a bigger picture. These values are used for an image that is 1000x1000px big. Then select “Move” and change the values to 30 (Radius) and a strength of 0.3. (it was not really effective on my nose though because I have a ‘flat’ nose…haha).Īnyway, click on Filter -> Distort -> IWarp. We need to have bigger eyes and make the nose more connected to the eyes. ![]() We will have to work on the distortion of the face first. Duplicate your photo and work on the copy.
