This MATLAB function returns the largest value of the 32-bit signed integer type. This MATLAB function converts the grayscale, RGB, or binary image I to data type uint16, rescaling or offsetting the data as necessary. Certain MATLAB functions, including the find, all, any, conv2, convn, fft2, fftn, and sum functions accept uint8 or uint16 data but return data in double precision format. All my attempts with typecast and cast still map value 0 (uint16) to 0 (int16). It will convert your number to 16-bit half precision format. The goal is to map these values to the 0-65535 range, since uint16 can This MATLAB function converts the grayscale, RGB, or binary image I to data type uint16, rescaling or offsetting the data as necessary. Convert x and y coordinates from double to uint16. The image function In this section we will introduce the various datatypes available in Matlab thatareusedforstoringintegers. Values outside this range saturate on overflow, namely they are mapped to 0 or 65535 if they are outside the range. MATLAB ® has many functions to convert values from one data type to another for use in different contexts. This MATLAB function returns the data in A converted to the data type (class) newclass, where newclass is the name of a built-in data type compatible with A. Numeric classes in MATLAB ® include signed and unsigned integers, and single-precision and double-precision floating-point numbers. 创建对象有些数组创建函数允许您指定数据类型。例如， zeros(100,'uint16') 创建一个由 uint16 类型的零值组成的 100×100 矩阵。如果您有一个不同类型（如 double 或 single）的数组，则可以使用 This MATLAB function converts the grayscale, RGB, or binary image I to data type uint16, rescaling or offsetting the data as necessary. raw",'r'); %默认是小端存 This MATLAB function returns the built-in uint16 value of fi object a, based on its real world value.

If you plan to do sophisticated image processing on uin t8 or uint16 data, consider To convert a 32-bit image to a uint16 image while preserving the grayscale values, you need to scale the pixel values appropriately. 8Chapter 1 uint8, uint16, uint32, uint64 Convert to unsigned integer 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. Variables in MATLAB of data type (class) uint16 are stored as 2-byte (16-bit) unsigned integers. For non integer values, Scilab's uint16() I am assuming that you have used "Data Type Conversion" block, and the conversion to "uint16" resulted in unexpected values due to the default integer rounding mode being set to "floor" in Block If the input image is of class uint16, the output image is identical to it. An image whose data matrix has class uint8 is called an 8-bit image; an image whose data matrix has class uint16 is called a 16-bit image. This MATLAB function converts the bit patterns of X to the data type specified by newtype without changing the underlying data.
