Synopsis

HxImageRep HxCrossVal(HxImageRep img, HxValue val)

Input

HxImageRep img

The input image

HxValue val

The input value

Return value

HxImageRep

The cross product of the input image with the input value, pixel wise.

Description

The function HxCrossVal takes the cross product of the input image pixels with the input value. pixel-by-pixel basis. If pixel one is given by (a,b,c) and the input value is given by (d,e,f), the cross product is defined as (bf-ce, cd-af, ae-bd). Only vector pixel types of dimension 3 are valid. The dimensionality of the input value should also be 3.

Remarks

Valid image types and input values

The dimensionality of the input value and the pixel dimensionality of the input image should both be 3.

Overflow error
