![]() To address this need, we present here PyImageJ, a Python-based package built on ImageJ2 (ref. ImageJ supports an active community of software developers who produce and maintain these three extension types, which in recent years include deep-learning capabilities 4. Additionally, the functionality of ImageJ has been extended through the use of plugins - new features written in Java and accessible directly from ImageJ, capable of bringing cutting edge technologies to the ImageJ platform. ![]() All of these operations can be combined to construct complex workflows in the form of macros and scripts. ImageJ allows researchers to perform a variety of image-processing and analysis tasks such as edge detection, tiled image stitching, object and cell lineage tracking morphological operations such as skeletonization and various data projections. As the Python software library has grown over the years to address new image-processing needs, so too has ImageJ - a Java-based open-source software package and platform widely used for scientific image analysis. Increasingly, these innovations are written in the Python programming language, making use of its extensive software library (for example, NumPy 2 and SciPy 3) and its accessibility to researchers at various programming proficiency levels. Even though you might not notice any problems by eye, the tips outlined here for acquiring and storing images can improve.New advancements in biological image processing, such as object segmentation, tracking 1 and machine-learning frameworks, have enabled researchers to extract more information and ask additional questions of their image data.

Just be sure that you don’t run any analysis on images that you’ve saved for presentation! You can also add a RescaleIntensity module prior to saving, which may help to make your cells visible. If you want to save a color image for presentation, you can use the “RGB” color mode in the GrayToColor module. This format is what we typically use for presentations. If you want to save images for presentation, CellProfiler also allows you to save. When you open the image in ImageJ, CellProfiler, or another analysis software, however, you can adjust the contrast to change how the image is displayed, which will allow you to see your cells. Most microscopy images will have the vast majority of pixels in the very, very low end of these spectrums, if you try to view the image using a typical image browser like Preview on a Mac, you’ll just see a black image. An 8-bit tiff image can have intensity values ranging from 0-255 at each pixel and a 16 bit tiffs can range from 0-65,535. ![]() The outputted tiff image is very dark because the intensity values at each pixel are likely very small relative to the potential scale of possible intensities. This allows you to create an image stack for opening in ImageJ or other image analysis programs. Hi CellProfiler, in order to have multiple channels combined into a single image to save, you can use the GrayToColor module.
