Evaluate variance, 16X16 block
SSE2
| FwStatus | fwiVariance16x16_8u32s | ( | const Fw8u * pSrc, Fw32s srcStep, Fw32s * pVar ); |
| pSrc | Pointer to a block of DCT coefficients. | |
| pVar | Pointer to a variance value. | |
| srcStep | Source buffer step size (width of the buffer in bytes). |
This function evaluates the variance of a 16X16 block of unsigned elements. The result is stored in integer Var.
