inline

Member Function Documentation

computePatchOrientation()

float pic::SIFTDescriptor::computePatchOrientation ( Image *  imgGrad, int  x0, int  y0  )

inline

computePatchOrientation

Parameters

imgGrad
x0
y0

Returns

get()

float* pic::SIFTDescriptor::get ( Image *  imgGrad, int  x0, int  y0, float *  desc = NULL  )

inline

get computes a descriptor at position (x0,y0) with size n for a given image gradient imgGrad.

Parameters

img	is the gradient of the input image
x0	is the x-coordinate where to compute the descriptor
y0	is the y-coordinate where to compute the descriptor
desc	is the output descriptor, if it is NULL, memory will be allocated

Returns

it returns a pointer to the descriptor

getDescriptorSize()

int pic::SIFTDescriptor::getDescriptorSize ( )

inline

getDescriptorSize returns the descriptor size.

Returns

the descriptor size.
