  1. Hi All, Using ImageJ 1.44 on linux, for some reason when I have an RGB image stack, it loads into ImageJ as 8bit grayscale rather than RGB. If I check a single image of the stack, it loads correctly in RGB, but when loading the full stack, it's converted to grayscale. I made sure not to check convert to 8bit, so that's not the problem. . Maybe this i
  2. The real weighting used for rgb to grayscale conversion is 0.3R+0.6G+0.11B. these weights arent absolutely critical so you can play with them. I have made them 0.25R+ 0.5G+0.25B. It produces a slightly darker image. NOTE: The following code assumes xRGB 32bit pixel forma
  3. RGB stands for Red-Green-Blue, each channel is 8 bits. RGB is 24 bit color. Greyscale is one 8 bit channel of intensity. When you go RGB -> Greyscale you lose 1/3 of the information of the image

The colors in RGB images (24-bit with 8-bits for each of the red, green and blue channels) are used to show multi-channel images. The colors are designed to reflect genuine colors (i.e. the green in an RGB image reflects green color in the specimen). There are several RGB functions in Fiji. Native functions can be found in Image › Color imagej. stmfiji October 17, 2016, 6:45pm #1. My goal is to convert a 3 channel 16-bit RGB image into a single channel 16-bit image of average intensity gray values. Using the GUI I do: [Stk] button with red arrow triangle down | Z-project | Average Intensity [OK] In the MacroRecorder that gives me only : run (Grays); I believe that is wrong. To the left of the color palette is a grayscale ramp that goes from pure black to pure white. Double-clicking on a color brings up the Color Selector, shown on the right in the illustration. Use the sliders to specify the RGB values of the foreground or background color. To get precise colors, manually change the values in the text boxes Converts to 8-bit grayscale. The active image must be 16-bit grayscale, 32-bit grayscale, 8-bit color or RGB color. ImageJ converts 16-bit and 32-bit images to 8-bits by linearly scaling from min-max to 0-255, where min and max are the two values displayed in the Image>Adjust>Brightness/Contrast command • Grayscale is the same as Color except it shows the channels in grayscale. How to control the intensity and/or color of each channel: 1. Switch to Color mode using the pull-down menu. 2. Select the channel you want to change. 3.

best on grayscale images, although there is an experimental color threshold tool built in to ImageJ that you can try as well. 3) You can use Analyze Plot Profile to create a plot of intensity values across features in your image. In the example below, the plot gives the intensity values along the line drawn across three cell processes Define two operations, one to convert a color image to a grayscale image and one for the backward conversion. To get luminance of a color use the formula recommended by CIE : L = 0.2126 × R + 0.7152 × G + 0.0722 × Colour Analysis Tools in ImageJ 11 July 2007 Jacqui Ross Digital Images = arrays of pixels (picture elements). Each has a value and is made up of bits (8bit, 12bit, 16bit That means anywhere we see 0 in the greyscale image, we actually colour the pixel rgb (68,1,86). Anywhere we see 1 in the greyscale it maps to rgb (68,2,85). Presumably you can copy that file to your production machine and you can choose any one of Matplotlib s colormaps Returns a luminosity histogram for RGB images and null for float images. For 8-bit and 16-bit images, returns an array with one entry for each possible value that a pixel can have, from 0 to 255 (8-bit image) or 0-65535 (16-bit image)

Color imagesuse 8-bit encoding for each channel (e.g. RGB: 256 intensity values for red, green, and blue). Pixels in grayscale imagesmay be encoded as 8-bit integer (256 intensity levels), 16-bit integer (65536 intensity levels), or 32-bit float (decimal number) values When converting an RGB image to grayscale, we have to take the RGB values for each pixel and make as output a single value reflecting the brightness of that pixel. One such approach is to take the average of the contribution from each channel: (R+B+C)/3. However, since the perceived brightness is often dominated by the green component, a. ImageJ handles 4 dimensional images using a stack. 3 dimensions: X, Y, intensity The 4th dimension can be time or wavelength channel. Example 1: A set of grayscale microscope images taken over several minutes (grayscale video) Example 2: A set of grayscale images acquired with different wavelength filters and a filter wheel Understanding Grayscale Image Structure. Grayscale images only have one channel! That's it! The problem. Quoting the Pytorch documentation:¹ All pre-trained models expect input images normalized in the same way, i.e. mini-batches of 3-channel RGB images of shape (3 x H x W)..

  5. Open a color (RGB) image and select the POINTCROSS tool in the toolbar of Imagej. Choose the first color cluster (e.g. A) and define the color by clicking on the image. Choose the second color cluster (e.g. B) and define the color by clicking on the image
  6. ImageJ does a perfect job for this, but my IM does not (version 6.3.3). More specifically, IM saves BMP only in RGB mode even with -colorspace Gray or -type Grayscale options specified, resulting in 3x larger file size than desired (because of the three redundant channels R=G=B=256 grayscale)
  7. Grayscale as single channels of multichannel colour images Colour images are often built of several stacked colour channels , each of them representing value levels of the given channel. For example, RGB images are composed of three independent channels for red, green and blue primary colour components; CMYK images have four channels for cyan.

ImageJ can handle a video that has a few hundred images, but cramming in longer videos can slow or crash the program. As you open your video, you'll be offered an option to convert it to 8-bit grayscale or RGB, and to use virtual stack rather than loading your whole video into memory ImageJ is an intersting Java based image processing application inspired by NIH Image for the Macintosh. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.1 or later virtual machine median filtering and thresholding on both 8-bit grayscale and RGB color images. Interactively adjust. Adding color to a grayscale image is a neat little effect you see all over the place. Now, this isn't to be confused with taking a color image and removing its color, only to add some of it back in certain places. This technique is entirely different. What I'm going to show you today is how to apply a new color to a naked image, so to speak The image at right is a thumbnail version of a digital grayscale image.The image is a rectangular tiling of fundamental elements called pixels.A pixel (short for picture element) is a small block that represents the amount of gray intensity to be displayed for that particular portion of the image.For most images, pixel values are integers that range from 0 (black) to 255 (white) Since its an RGB image, so it means that you have add r with g with b and then divide it by 3 to get your desired grayscale image. Its done in this way. Grayscale = (R + G + B / 3) For example: If you have an color image like the image shown above and you want to convert it into grayscale using average method. The following result would appear

ImageJ is a public domain, Java-based image processing program developed at the National Institutes of Health. ImageJ was designed with an open architecture that provides extensibility via Java plugins and recordable macros. Custom acquisition, analysis and processing plugins can be developed using ImageJ's built-in editor and a Java compiler Copy to Clipboard. Here is how to get the hue and saturation image for a grayscale image: hueImage = zeros (size (grayscaleImage)); saturationImage = zeros (size (grayscaleImage)); Of course, they are both all zero for a monochrome, grayscale image

It can read many image formats including TIFF, PNG, GIF, JPEG, BMP, DICOM, FITS, as well as raw formats. ImageJ supports image stacks, a series of images that share a single window, and it is multithreaded, so time-consuming operations such as image file reading can be performed in parallel. The coefficients a, b, c and d in the equation above are defined within ImageJ based on the mean grayscale values, x, and expected doses input during calibration. Future film measurements can use this calibration function by measuring the mean grayscale values and substituting each into Eq 1 to solve for dose (y). This analysis can be scripted. My only complaint so far is that there is little focus on color (RGB) images. The authors do quite a bit of work with multichannel data, but there is little to do with handling RGB images (things like adding a color lookup table to a grayscale image, using the Channels Tool with hyperstacks, etc)
