I have got a image with multiple thresholds (attachment).
Is it possible to negate all but one of the thresholds - e.g. have only the purple layer - such that the rest of the threshold labels are not visible and only the purple one remains?
thresh = multithresh(I,4);
sI = imquantize(app.image,thresh);
RGB = label2rgb(sI);
figure;

Hi,
The multithresh will return multiple threshold value in a vector to be used. Since you want to use only a single threshold for displaying you can select that threshold value from the vector thresh and pass only that value to imquantize in the ‘thresh’ field. This will create only single label in the resulting image.
