Best Answer. You can convert uint8 and uint16 data to double precision using the MATLAB function, double. However, converting between storage classes changes the way MATLAB and the toolbox interpret the image data. If you want the resulting array to be interpreted properly as image data, you need to rescale or offset the data when you convert it

If the input is a double, Y is in the range [16/255 235/255] and Cb and Cr are in the range [16/255 240/255]. If the input is uint16, Y is in the range [4112 60395] and Cb and Cr are in the range [4112 61680]. Code Generation support: Yes. MATLAB Function Block support: Yes.

Creation. Some array creation functions allow you to specify the data type. For instance, zeros(100,'int8') creates a 100-by-100 matrix of zeros of type int8. If you have an array of a different type, such as double or single, then you can convert that array to an array of type int8 by using the int8 function.

1.uint8, uint16 with double. To save storage space, matlab provides a special data type uint8 (8 unsigned integer) of the image, the image stored in this manner is referred to as 8-bit image. matlab read image data is uint8, the values generally used in matlab double type (64-bit) operations. Summarize: uint8, uint16-- storage, display
