Solved Uint8 is a data type in MATLAB. uint8's are integers
Create a complex number of the data type double. p = 1+2i p = 1.0000 + 2.0000i Convert A to the same data type and complexity as the variable p.

Description i = uint8 (x) converts the vector x into an unsigned 8-bit integer. x can be any numeric object (such as a double ). The elements of an uint8 range from 0 to 255. The result for any elements of x outside this range is not defined (and may vary from platform to platform). If x is already an unsigned 8-bit integer, uint8 has no effect.

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 uint8 by using the uint8 function. Syntax Y = uint8 (X) Description example Y = uint8 (X) converts the values in X to type uint8. Values outside the range [0,2 8 -1] map to the nearest endpoint. Input Arguments expand all

1 Link Try this: Theme Copy % First convert G to a 3-D variable. G = cat (3, G, G, G); % Now convert it to uint8. It will clip values outside the range 0-255, and will round values in the range. G = uint8 (G); meenu v on 17 Sep 2020 on 17 Sep 2020 There are other ways of scaling, it just depends on what you want to do and what you're starting with.

Why is there an error with type "double"? 4 Comments Show 2 older comments DGM on 21 May 2022 Ran in: The short answer is "neither" It's certainly arguable that 210 is not white. You could say it's a light gray maybe. Likewise, 20 is not black, but maybe you can say it's dark gray. It all depends on how specific "black" and "white" mean in context.

Syntax i = uint8 (x) i = uint16 (x) i = uint32 (x) i = uint64 (x) Description i = uint* (x) converts the vector x into an unsigned integer. x can be any numeric object (such as a double ). The results of a uint* operation are shown in the next table. A value of x above or below the range for a class is mapped to one of the endpoints of the range.

Double data type in image processing ( difference between double and uint8) YouTube
You can convert uint8 and uint16 image data to double using the MATLAB ® double function. However, converting between data types 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.

Introduction (Image Processing Toolbox) 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.
MATLAB CONVERT DOUBLE TO UINT8
1 uint8 computations have a much larger rounding error than double. What you are seeing is because MATLAB expects double images to be in the range [0,1]. If your images have a larger range, they might end up clipped in some algorithms.

1. Link. It really depends on how you want to do it, and if you have values outside the 0-1 range. I'll just add a third method: mat2gray (). Now, look at this demo and see how Walter's suggestion, Jan's suggestion, and mat2gray () produce 3 different uint8 matrices: Theme. Copy. m = 5*rand (4) maxValue = max (m (:));
