Function Documentation

MtkSmoothData()

MTKt_status MtkSmoothData	(	const MTKt_DataBuffer *	Data,
		const MTKt_DataBuffer *	Valid_mask,
		int	Width_line,
		int	Width_sample,
		MTKt_DataBuffer *	Data_smoothed
	)

Smooth the given array with a boxcar average of the specified width. The algorithm is similar to the IDL smooth routine. Smoothed data is type float.

Returns

MTK_SUCCESS if successful.

Example:

In this example we smooth data with mask valid_mask and smoothing window widths width_line and width_sample. Output is data_smoothed.

status = MtkSmoothData(&data, &valid_mask, width_line, width_sample, &data_smoothed);

Note

Parameters

[in]	Data	Data. (float)
[in]	Valid_mask	Mask inidicating where data is valid. (uint8)
[in]	Width_line	Width of smoothing window along line dimension. Must be and odd number.
[in]	Width_sample	Width of smoothing window along sample dimension. Must be an odd number.
[out]	Data_smoothed	Smoothed data. (float)
