Variable Documentation

void(* ne10_img_boxfilter_rgba8888) (const ne10_uint8_t *src, ne10_uint8_t *dst, ne10_size_t src_size, ne10_int32_t src_stride, ne10_int32_t dst_stride, ne10_size_t kernel_size)

Box blur of RGBA8888 image data.

Parameters

[out]	*dst	pointer to the output buffer
[in]	*src	pointer to the input buffer
[in]	src_sz	size of the source image
[in]	src_stride	source stride
[in]	dst_stride	destination stride
[in]	kernel	blurring kernel size (with sides between 1 and 65535 pixels wide)

Applies a box filter (also known as a box blur) to an input image in the RGBA8888 format, producing a blurred output image of the same size and format. The blurring kernel is anchored at its center. When values must be obtained from beyond the source image boundaries, zero-valued pixels are assumed.

Points to ne10_img_boxfilter_rgba8888_c or ne10_img_boxfilter_rgba8888_neon. This is an out-of-place algorithm.
