WebApr 13, 2024 · Direct mapping like this is what you'd use when you have an actual indexed image (e.g. a GIF file). Scaled mapping is what you might be used to if you just want to display a single-channel image or data in pseudocolor with imagesc() or imshow(). While ind2rgb() alone works for direct mapping, the attached function does the latter. Webmaximum values. That is, extrema are the points of a function where it is the largest and the smallet. We can identify two types of extrema - local and global. Global extrema are the largest and smallest values that a function takes on over its entire domain, and local extrema are extrema which occur in a speciﬁc neighborhood of the function. earn your degree
