Method Details

convert_F32_U16

public static void convert_F32_U16(GrayF32 src,
 int fractionBits,
 GrayU16 dst)

Converts a floating point image with all positive values into a 16-bit image using fixed-point math. The number of bits dedicated to the fractional component is configurable. If 8-bits are allocated then the max integer value is 256 and the fractional resolution is 1/256 Limitations:

• Fractional bits specifies accuracy of fractional component. FR=2**fractional_bits
• src must have values with in the range 0 ≤ x ≤ 2**(16-fractional_bits)
• fractional component will only be saved to within 1/FR resolution
• To reduce discretization bias rounding is done instead of flooring

Parameters:

src - (Input) Input F32 image

fractionBits - (Input) Number of bits allocated to the fractional component

dst - (Output) Output U16 image

convert_U16_F32

public static void convert_U16_F32(GrayU16 src,
 int fractionBits,
 GrayF32 dst)

Inverse of convert_F32_U16(GrayF32, int, GrayU16)

Parameters:

src - (Input) Input U16 image

fractionBits - (Input) Number of bits allocated to the fractional component

dst - (Output) Output F32 image
