Function Documentation

MtkDownsample()

MTKt_status MtkDownsample	(	const MTKt_DataBuffer *	Source,
		const MTKt_DataBuffer *	Source_mask,
		int	Size_factor,
		MTKt_DataBuffer *	Result,
		MTKt_DataBuffer *	Result_mask
	)

Downsample data by averaging pixels.

Returns

MTK_SUCCESS if successful.

Example:

In this example we downsample source with source_mask by size_factor. The result is stored in result with result_mask.

status = MtkDownsample(&source, &source_mask, size_factor, &result, &result_mask);

Note

Parameters

[in]	Source	Source data. (float)
[in]	Source_mask	Valid mask for source data. (uint8)
[in]	Size_factor	Number of pixels to aggregate along each dimension.
[out]	Result	Downsampled result. (float)
[out]	Result_mask	Valid mask for result. (uint8)
