Detailed Description

Accumulates a squared value from an input image to an output image.

Accumulate squares is computed by [R00007]:

\[ accum(x,y) = saturate_{int16} ( (uint16) accum(x,y) + (((uint16)(input(x,y)^2)) >> (shift)) ) \]

Where \( 0 \le shift \le 15 \)

The overflow policy used is VX_CONVERT_POLICY_SATURATE [R00008].

Function Documentation

vx_node VX_API_CALL vxAccumulateSquareImageNode	(	vx_graph	graph,
		vx_image	input,
		vx_scalar	shift,
		vx_image	accum
	)

[Graph] Creates an accumulate square node.

Parameters

[in]	graph	The reference to the graph [R00274].
[in]	input	The input `VX_DF_IMAGE_U8` image [R00275].
[in]	shift	The input `VX_TYPE_UINT32` with a value in the range of \( 0 \le shift \le 15 \) [R00276].
[in,out]	accum	The accumulation image in `VX_DF_IMAGE_S16` [R00277].

Return values

vx_node A node reference. Any possible errors preventing a successful creation should be checked using vxGetStatus
