Do you think the image background could somehow be improved so that the contrast could be increased without introducing artefacts? (I cannot repeat the assay so these images are all I have to work with )

The background itself is not a problem, it’s the lack of unique features to distinguish cells from artifacts that is lacking. Most methods would rely on enhancing edges, but considering you have about as many artifacts as you have cells, they will be equally enhanced and you’ve moved the problem down to “how to reduce the other artifacts now that the contrast is better”. It’s a Russian Dolls kind of problem…

In Fiji, press CTRL + SHIFT + N (Or CMD instead of CTRL on Mac) to bring up the script editor, and copy paste the code below, then hit run. It will ask you for a file, and you should point it to your image.

In the case that a user would come to our facility with such data, we would be forced to refuse helping them analyze it, and would proceed to help them optimize their imaging, usually with a small batch and some quick testing before ramping up the acquisition to a full experiment.

If you’re doing this visually, you can blur the image a lot using a Gaussian Filter and dividing the original image by it.

Our Ring Lights offer shadowless illumination, intensity, power and 5x lifetime over fluorescents. Ring Lights are essential for lighting specular or diffused surfaces. Our Metabright Ring Lights are built with high density LEDs that create bright illumination of surfaces for a wide spectrum of Machine Vision inspection purposes. VLT Ring Lights are specially designed to project an even 360 degree overlapping ring of light from camera to lens. In most Machine Vision front lighting applications our ring lights are a simple, low cost solutions to camera lighting. All of the Ring Lights we offer for Machine Vision are just as robust and employ proprietary thermal management technology to dissipate internal die temperature externally. Some of our Ring Lights provide the ability to mount the Ring Light directly on the camera, because of three 1/4-20 tapped holes and our Ring Lights are compatible with most camera brackets for direct mounting. RING LIGHTS (DIRECT LIGHTING) These Ring Lights for Machine Vision are equipped with high-density LED arrays in a ring shape. Direct light is radiated with focus on the center of the workpiece from any angle. LDR2 Series; SQR Series. LOW-ANGLE RING LIGHTS (DIRECT LIGHTING) These Low-angle Ring Lights for Machine Vision provide light from a low angle to the center section. The edges of the workpiece and any engraving/damage on the metal surface can be highlighted clearly. LDR2-LA Series; LDR-LA1 Series. RING LIGHTS (INDIRECT LIGHTING) These Ring Lights achieve uniform illumination through diffused light. They are ideal for Machine Vision applications where the entire workpiece must be illuminated evenly. HPR2 Series; LFR Series; LKR Series. LOW-ANGLE RING LIGHTS (INDIRECT LIGHTING) These Low-angle Ring Lights for Machine Vision allow the edges of the workpiece and engraving or damage on surfaces to be detected through low-angle diffused light. FPR Series. NEAR AXIAL RING LIGHT Our near axis Ring Light provides extreme intensity lighting for working distance in Machine Vision. Our Ring Lights can be configured for wavelength and other specifications. MB-RL Series; MB-DRL Series. HALF CIRCLE OFF-AXIS RING LIGHTS The off-axis Ring Light (darkfield) provides a near horizontal plane of light, useful for highlighting surface defects. The half circle is flexible to illuminate a fixed object at a desired angle and provides lighting from a low angle, ideal for Machine Vision. OARL-SC2 Series. 2 RING OFF-AXIS RING LIGHTS This MetaLight™ two ring off-axis Ring Light provides a near horizontal plane of light which is useful for highlighting surface defects, illuminating specular surfaces, and side lighting prominent target features. An additional one ring of LEDs at a larger incident angle allows flexibility in target illumination. Our Ring Lights can be configured for wavelength and other specifications. DOARL202 Series. For more information and advice please contact us through an inquiry. APPLICATIONS Machine vision; Label identification; Direct part marking identification; Surface inspection and finishes; Microscopic stage illumination; Solder joint inspection; Components identification; Molded part features; Close-up, near-shadowless single light illumination applications. FEATURES Ideal for Machine vision applications; Exclusive prealignment process aims and then thermally pots each LED; Configurable for various wave lengths including IR, UV and RGB; Continues, dimming, and strobbing controllability modes; Homogenous light output; Provides ON-axis illumination; Solid one-piece machined aluminum housings and thermal potting assures long life performance even in rugged environments.

Another issue that the images are JPEG compressed and the JPEG artifacts are roughly the size of your cells. Those artifacts will be enhanced as well… Ideally the camera attached to the microscope can save images in an uncompressed way. This is something your group should look into if they wish to do automated quantitative analysis using that microscope.

Hello. I am trying to preprocess some images for segmentation using FIJI but I am struggling due to noise, especially light artefacts. The images were obtained using a brightfield microscope. The purpose of the images is to investigate cell migration, so I am interested in the gap between the two sides rather than quantifying cell counts. I have 95 images and have outlined most of them manually, but the contrast is so poor and there is so much noise that I highly doubt the accuracy of my approach, so I would like to know if the images can be preprocessed such that I could accurately used an automated segmentation method. I have carried out a pseudo flat field correction using the BioVoxxel plugin to address the shading discrepancy in some of the images, but I am not sure what else to do. Thank you in advance for any help!

Unfortunately I would have to agree with that remark, and unfortunately I am afraid that no amount of preprocessing is going to be able to help you. These are issues that should be adressed on the image acquisition and microscopy side.
