In digital image processing, thresholding is the simplest method of segmenting images. From a grayscale image, thresholding can be used to create binary images. See more The simplest thresholding methods replace each pixel in an image with a black pixel if the image intensity $${\displaystyle I_{i,j}}$$ is less than a fixed value called the threshold $${\displaystyle T}$$, … See more Multi-band images Color images can also be thresholded. One approach is to designate a separate threshold for each of the RGB components of the image and … See more • Pham N, Morrison A, Schwock J et al. (2007).

WebApr 12, 2024 · Answers (1) Since, you already have exported the createMask function by thresholding a baseline image having grass cover, you can use the function with other RGB images as the output of the function is a binary (BW) along with RGB (maskedRGBImage) image. WebImage thresholding is a simple, yet effective, way of partitioning an image into a foreground and background. This image analysis technique is a type of image segmentation that isolates objects by converting grayscale images into binary images. Image thresholding is most effective in images with high levels of contrast.
