Detailed Description

Normalize the pixel intensities of an image between two ranges.

Function Documentation

cudaNormalize() [1/4]

cudaError_t cudaNormalize	(	float *	input,
		const float2 &	input_range,
		float *	output,
		const float2 &	output_range,
		size_t	width,
		size_t	height
	)

Normalize the pixel intensities of a floating-point grayscale image between two scales.

For example, convert an image with values between [0,1] to [0,255]

Parameters

input_range	the range of pixel values of the input image (e.g. [0,1])
output_range	the desired range of pixel values of the output image (e.g. [0,255])

cudaNormalize() [2/4]

cudaError_t cudaNormalize	(	float3 *	input,
		const float2 &	input_range,
		float3 *	output,
		const float2 &	output_range,
		size_t	width,
		size_t	height
	)

Normalize the pixel intensities of a float3 RGB/BGR image between two scales.

For example, convert an image with values between [0,1] to [0,255]

Parameters

input_range	the range of pixel values of the input image (e.g. [0,1])
output_range	the desired range of pixel values of the output image (e.g. [0,255])

cudaNormalize() [3/4]

cudaError_t cudaNormalize	(	float4 *	input,
		const float2 &	input_range,
		float4 *	output,
		const float2 &	output_range,
		size_t	width,
		size_t	height
	)

Normalize the pixel intensities of a float4 RGBA/BGRA image between two scales.

For example, convert an image with values between [0,1] to [0,255]

Parameters

input_range	the range of pixel values of the input image (e.g. [0,1])
output_range	the desired range of pixel values of the output image (e.g. [0,255])

cudaNormalize() [4/4]

cudaError_t cudaNormalize	(	void *	input,
		const float2 &	input_range,
		void *	output,
		const float2 &	output_range,
		size_t	width,
		size_t	height,
		imageFormat	format
	)

Normalize the pixel intensities of an image between two scales.

For example, convert an image with values between [0,1] to [0,255]

Parameters

input_range	the range of pixel values of the input image (e.g. [0,1])
output_range	the desired range of pixel values of the output image (e.g. [0,255])
format	the image format - valid formats are gray32f, rgb32f/bgr32f, and rgba32f/bgra32f.
