Arithmetic Addition

Detailed Description

Performs addition between two images.

Arithmetic addition is performed between the pixel values in two VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16 images [R00011]. The output image can be VX_DF_IMAGE_U8 only if both source images are VX_DF_IMAGE_U8 and the output image is explicitly set to VX_DF_IMAGE_U8 [R00012]. It is otherwise VX_DF_IMAGE_S16 [R00013]. If one of the input images is of type VX_DF_IMAGE_S16, all values are converted to VX_DF_IMAGE_S16 [R00014]. The overflow handling is controlled by an overflow-policy parameter [R00015]. For each pixel value in the two input image [R00016]s:

\[ out(x,y) = in_1(x,y) + in_2(x,y) \]
