WebOct 21, 2024 · Intensity Slicing. This is a simple case of pseudocolor image processing. It’s also called density slicing or color coding. Imagine a grayscale image as a 3D function with the intensity being the third dimension. Placing a plane parallel to the horizontal plane for the pixel position coordinates would “slice” the image into two parts. WebDescription. X = grayslice(I, n) thresholds the intensity image I returning an indexed image in X. grayslice uses the threshold values:. X = grayslice(I, v) thresholds the intensity image I using the values of v, where v is a vector of values between 0 and 1, returning an indexed image in X.

WebX = grayslice(I,N) converts a grayscale image to an indexed image by using multilevel thresholding approach. The function automatically calculates the threshold values based on N.To learn more about threshold calculation, see Algorithms. WebUse grayslice and construct your own colormap. Plot the original and sliced image in the same figure. (If the "original" image also displays in pseudocolor, it is because the computer display is using the same four-level colormap for both images. In this case, you should convert the sliced image to RGB before displaying.) ...
