QuantFwdRawTableInit_JPEG | Modifies raw quantization tables in accordance with quality factor. |
QuantFwdTableInit_JPEG | Prepares quantization tables in a format suitable for an encoder. |
QuantFwd8x8_JPEG | Performs quantization of an 8x8 block of DCT coefficients. |
QuantInvTableInit_JPEG | Prepares quantization tables in a format suitable for a decoder. |
QuantFwd8x8_JPEG | Performs dequantization of DCT coefficients in 8x8 block |
