Close the Threshold dialog window without clicking any of the buttons. This study aims to obtain an overview of the color palette (310 colors) after processing with the default threshold method in ImageJ v1.53s or FIJI (ImageJ2). the color image to 3 different images ImageColorSplit Channels.

Otherwise, you need to know the color of all of the objects in your images and rerun the color threshold multiple times per image. The image can be converted to a binary image via the menu command Image Type 8-bit. The background of the thresholded image can be made light or dark. The Color space option allows you to choose between HSB, RGB, Lab, and YUV. Adjust the sliders so that the dark, low-value pixels that represent water turn red, but those that represent land don't change. Because it would be much simpler to just normally threshold the original image and get the object area that way. The Threshold color option allows you to choose between Red, White, Black, or B&W as the thresholding color. The Threshold dialog window allows you to highlight pixels in an image that have values within a range you define. This action converts each pixel's color information into a brightness measurement. Choose Image > Type > 8-bit to convert the image to grayscale.NOTE: the techniques described here do not work as well on the MODIS images that you used in the previous section, as there is not enough contrast in the MODIS images. As the ranges of pixel values that represent land and water are unique, you can manipulate ImageJ to highlight the pixels that represent water in each image, and measure the area it covers. If the color information for each pixel is converted to grayscale, the dark pixels representing water will have low values and the lighter pixels that represent land will have higher values. This module can be used to detect objects of. In these images, pixels that represent water are much darker than pixels that represent land. The Color Threshold module is used to remove parts of the image that fall within a specified color range.
