Member Function Documentation

void CCamTile::CalcDiffValue (  const uchar *  src  )

Calculate absolute value of difference. Assuming 'src' refers to a Delta panel, calculate the sum of the absolute difference.

void CCamTile::CalculateForward (  uchar *  dst, uchar *  src )

Perform forward DCT calculation. Parameters: dst  Destination buffer; uses out_offsets src  Source buffer; used in_offsets

void CCamTile::CalculateInverse (  uchar *  dst, uchar *  src )

Perform inverse DCT calculation. Parameters: dst  Destination buffer; uses in_offsets src  Source buffer; used out_offsets Performs reverse DCT operation; note that the in/out_offsets are also swapped.

void CCamTile::ClearInTile (  uchar *  dst  )

Clear tile. This sets the 64 pixels of the input tile to a value of 128.

void CCamTile::ClearOutTile (  uchar *  dst  )

Clear tile. This sets the 64 pixels of the output tile to a value of 128.

int CCamTile::CompareTile (  const void *  t1, const void *  t2 )  [static]

void CCamTile::CopyTile (  uchar *  dst, const uchar *  src )
