Image Filter

2D Image filtering/convolution. More...

Device pointer interface: Image filtering.
Parameters: [out] d_out The filtered output [in] xi Number of rows in input image [in] yi Number of columns in input image [in] d_in Input image [in] xf Number of rows in the input filter [in] yf Number of columns in the input filter [in] d_filter Input filter (on device) [in] type used to specify behavior near the boundaries -{Symmetric(1), Repeating(2), Circular(3), Value(4)} [in] value if type=4, this value is used for out of bounds [in] conv true for convolution, false for correlation [in] full true for full convolution, false otherwise [in] batchA Number of input images (gfor) [in] batchF Number of input filters (gfor)
afError	af_filter_S (float *d_out, unsigned xi, unsigned yi, const float *d_in, unsigned xf, unsigned yf, const float *d_filter, unsigned type, float value, bool conv, bool full, unsigned batchA, unsigned batchF)
	Single precision, Image filtering.
afError	af_filter_D (double *d_out, unsigned xi, unsigned yi, const double *d_in, unsigned xf, unsigned yf, const double *d_filter, unsigned type, float value, bool conv, bool full, unsigned batchA, unsigned batchF)
