* Revision history: * |
|
|
* * |
|
|
* 29.03.2002 interlacing speedup - used transfer strides instead of |
|
|
* manual field-to-frame conversion |
|
|
* 26.03.2002 interlacing support - moved transfers outside loops |
|
|
* 22.12.2001 get_dc_scaler() moved to common.h |
|
|
* 19.11.2001 introduced coefficient thresholding (Isibaar) * |
|
|
* 17.11.2001 initial version * |
