Function Documentation

PTK_Alg_StereoPP_MedianFilterSetParams()

void PTK_Alg_StereoPP_MedianFilterSetParams	(	PTK_Alg_StereoPP_MedianFilter_configParams *	cfg,
		PTK_Alg_StereoPP_MedianFilterObj *	cntxt
	)

Initialize median filter parameters.

Parameters

[in]	cfg	configuration parameters for median filter
[in]	cntxt	median filter algorithm context

Returns

PTK_Alg_StereoPP_MedianFilterConfig()

int32_t PTK_Alg_StereoPP_MedianFilterConfig	(	PTK_Alg_StereoPP_MedianFilter_configParams *	cfg,
		PTK_Api_MemoryReq *	memReq
	)

Computes the memory requirements based on the given algorithm configuration parameters.

Parameters

[in]	cntxt	Algorithm configuration parameters.
[in]	memReq	Memory requirements as specified below entry [0]: Memory for internal context. Best allocated from the fastest memory. entry [1]: Memory for internal point cloud. Best allocated from the fastest memory. entry [2]: Memory for the output buffer. The output buffer is allocated by the Application so this entry is just to communicate the output buffer size. No need to pass the memory to the library in the init call PTK_Alg_SfmOgmapInit().

Returns

• PTK_ALG_RET_SUCCESS, if successful
• < error code, otherwise

PTK_Alg_StereoPP_MedianFilterInit()

PTK_AlgHandle PTK_Alg_StereoPP_MedianFilterInit	(	PTK_Alg_StereoPP_MedianFilter_configParams *	cfg,
		const PTK_Api_MemoryRsp *	memRsp
	)

Initializes the library based on the given algorithm configuration parameters and allocated memory blocks.

Parameters

[in]	allParams	Algorithm configuration parameters.
[in]	memRsp	Memory blocks as specified below

Returns

• valid handle, if successful
• NULL, otherwise

PTK_Alg_StereoPP_MedianFilterGetMem()

int32_t PTK_Alg_StereoPP_MedianFilterGetMem	(	PTK_Alg_StereoPP_MedianFilterObj *	cntxt,
		uint8_t *	memPtr
	)

Get memory size.

Parameters

[in,out]	cntxt	Algorithm handle.
[in]	memory	block pointer

Returns

• required memory size

PTK_Alg_StereoPP_runMedianFilter()

void PTK_Alg_StereoPP_runMedianFilter	(	PTK_Alg_StereoPP_MedianFilterObj *	cntxt,
		int16_t *	disparityBuffer,
		int16_t *	outDisparityBuffer,
		int16_t	stride
	)

Run 2-D median filter.

Parameters

[in]	cntxt	algorithm handle
[in]	disparityBuffer	input disparity buffer
[out]	outDisparityBuffer	output disparity buffer
	[int]	stride stride of disparity buffer

Returns
