WebMay 16, 2016 · Learn more about image processing, lung Image Processing Toolbox, MATLAB Hello, I am working on the lung segmentation, I got the output after thresholding which is shown in figure. But my output is not correct, I am interested in the lung region only. WebAug 11, 2024 · Now, thresholding can be defined as a process in which each pixel is converted to either 0 or 255 depending on whether its value is greater than or less than a threshold value. If the value of the pixel is greater than the threshold value, then it is converted to 255 otherwise it is converted to 1. This is how thresholding works. shared ownership shipston on stour https://carriefellart.com
