Quantization Functions

This section describes Intel IPP functions that perform quantization, dequantization and preparation of quantization tables and are specific for JPEG codec. These functions are listed in Table “Quantization Functions”.

Quantization Functions
Function Base Name Description
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
