Hello. I need to measure the vegetation cover area of the green roof. I’m using Image J to measure them, and I’m new to Image J. I don’t find using “Color Threshold” as an excellent method to select all the vegetation at the same time because neither of the plants nor the substrates is in uniform color.

At the center of the color ramp are enlarged red, green, blue, cyan, magenta, and yellow colors for quick selection.

Use the sliders to specify the RGB ...

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.

选区 是 Image J以及其他图像处理软件 中的一种基本操作单元，只有建立了选区之后才能针对选区进行一些分析和计算。 比如，对图像中的每个物体记录一个选区，则可以通过统计选区数目来计数；也可以分析每个选区内的某些属性，比如依据选区进行划线、填充，测量该选区的面积、周长、直径 ...

Go to ImageJ r/ImageJ A community for the discussion of image analysis, primarily using ImageJ (and FIJI), a free, open source, scientific image processing and analysis program using Java, and is used worldwide, by a broad range of scientists.

I've also added a step that takes the binary selection and reapplies it to the original image and draws around the segmented region in red so that you can manually check that the process worked correctly. To use the code, just open a new script in imageJ (file > new > script), set the language to 'IJ1 Macro', paste the code below and press run.

If I have an image on ImageJ, how would I fill a particular selection with a certain colour? For instance, how would I fill this ellipse with let’s say, solid black so that a black ellipse is overlades the above imag…

How to select a ROI based on color? BW = roicolor (I,v) returns an ROI selected as those pixels in image I that match values in vector v. Load an indexed image X wth color map map. The color map has 128 colors. Display the indexed image. Create a binary mask image based on color. The mask is true for pixels with index in the range [10, 20].

From my experience and research you can't color threshold in a batch macro. You may be able to bring up the color threshold window but will have to make adjustments for each image. In the end I ended up going to Image-color-split channels and then used thresholding on the individual grey scale images that had the best representation for the ...

Use the standard ImageJ selection-brush-tool (or any other selection tool) to draw a selection on the region you want to modify. Press the f-button or hit f5 to fill the selection with the previously picked value. How do I change the color of a fill in ImageJ? Colors can be “picked up” from the Image>Color>Color Picker window using any tool.

Hi all, Very new to ImageJ and trying to create a macro for a repetitive process to try and quantify an area of a PAS image. I am using a color threshold to select area from a PAS image and want to create a macro to use on other images. The overall goal is to set a color threshold with HUE 130-255 and sat/bright 0-255. Then I want to select the area > clear outside for measurement. The problem ...
