Synopsis

HxImageRep HxNorm1 (HxImageRep img)

Return value

HxImageRep

The result of taking the city block distance norm of the input image.

Description

The function HxUnarySum takes the city block distance norm of every pixel value in the input image and stores it in the corresponding pixel of the output image. The city block distance norm of a scalar equals the absolute value of the scalar itself, while the city block distance norm of a vector equals the sum of the absolute value of the components of the vector. If the input is a vector image containing HxBytes, the output image is of the integer type.

Remarks

Possible errors

HxNorm1 can result in an overflow error.
