Image must be real and cannot be sparse. Image must be an intensity, RGB, or indexed image. Intensity or RGB image must be uint8, uint16, or double. MAP must be real, double, and cannot be sparse. MAP must be M-by-3 colormap. MAP has too many colors for 8-bit integer storage. X must have 2 dimensions. Invalid indexed image: an index falls outside colormap. Invalid indexed image: an index was less than 1. X must be uint8 or double. Internal problem: too many input arguments.
